The controller will interleave the buffers on write and split them on

+read. This means that Linux can DMA the data buffers to and from
host memory without changes to the page cache.
Also, the 16-bit CRC checksum mandated by both the SCSI and SATA specs
The IP checksum is weaker than the CRC in terms of detecting bit
errors. However, the strength is really in the separation of the data
-buffers and the integrity metadata. These two distinct buffers much

+What: lock_policy_rwsem_* and unlock_policy_rwsem_* will not be
+ exported interface anymore.
+When: 2.6.33
+Why: cpu_policy_rwsem has a new cleaner definition making it local to
+ cpufreq core and contained inside cpufreq.c. Other dependent
+ drivers should not use it in order to safely avoid lockdep issues.

+Problem: Files copied from sysfs appear empty or incomplete.
+Cause: Due to the way seq_file works, some tools such as cp or tar
+ may not correctly copy files from sysfs.
+Solution: Use 'cat' to read .gcda files and 'cp -d' to copy links.

+Kernel driver lp3944
+====================
+
+ * National Semiconductor LP3944 Fun-light Chip
+ Prefix: 'lp3944'
+ Addresses scanned: None (see the Notes section below)
+ Datasheet: Publicly available at the National Semiconductor website
+ http://www.national.com/pf/LP/LP3944.html
+
+Authors:
+ Antonio Ospite <ospite@studenti.unina.it>
+
+
+Description
+-----------
+The LP3944 is a helper chip that can drive up to 8 leds, with two programmable
+DIM modes; it could even be used as a gpio expander but this driver assumes it
+is used as a led controller.
+
+The DIM modes are used to set _blink_ patterns for leds, the pattern is
+specified supplying two parameters:
+ - period: from 0s to 1.6s
+ - duty cycle: percentage of the period the led is on, from 0 to 100
+
+Setting a led in DIM0 or DIM1 mode makes it blink according to the pattern.
+See the datasheet for details.
+
+LP3944 can be found on Motorola A910 smartphone, where it drives the rgb
+leds, the camera flash light and the lcds power.
+
+
+Notes
+-----
+The chip is used mainly in embedded contexts, so this driver expects it is
+registered using the i2c_board_info mechanism.
+
+To register the chip at address 0x60 on adapter 0, set the platform data
+according to include/linux/leds-lp3944.h, set the i2c board info:
+
+ static struct i2c_board_info __initdata a910_i2c_board_info[] = {
+ {
+ I2C_BOARD_INFO("lp3944", 0x60),
+ .platform_data = &a910_lp3944_leds,
+ },
+ };
+
+and register it in the platform init function
+
+ i2c_register_board_info(0, a910_i2c_board_info,
+ ARRAY_SIZE(a910_i2c_board_info));
defined; this list will expand as more and more SOC-containing
platforms are moved over to use the flattened-device-tree model.
- a) PHY nodes
-
- Required properties:
-
- - device_type : Should be "ethernet-phy"
- - interrupts : <a b> where a is the interrupt number and b is a
- field that represents an encoding of the sense and level
- information for the interrupt. This should be encoded based on
- the information in section 2) depending on the type of interrupt
- controller you have.
- - interrupt-parent : the phandle for the interrupt controller that
- services interrupts for this device.
- - reg : The ID number for the phy, usually a small integer
- - linux,phandle : phandle for this node; likely referenced by an
- ethernet controller node.
-
-
- Example:
-
- ethernet-phy@0 {
- linux,phandle = <2452000>
- interrupt-parent = <40000>;
- interrupts = <35 1>;
- reg = <0>;
- device_type = "ethernet-phy";
- };
-
-
- b) Interrupt controllers
-
- Some SOC devices contain interrupt controllers that are different
- from the standard Open PIC specification. The SOC device nodes for
- these types of controllers should be specified just like a standard
- OpenPIC controller. Sense and level information should be encoded
- as specified in section 2) of this chapter for each device that
- specifies an interrupt.
-
- Example :
-
- pic@40000 {
- linux,phandle = <40000>;
- interrupt-controller;
- #address-cells = <0>;
- reg = <40000 40000>;
- compatible = "chrp,open-pic";
- device_type = "open-pic";
- };
-
- c) 4xx/Axon EMAC ethernet nodes
-
- The EMAC ethernet controller in IBM and AMCC 4xx chips, and also
- the Axon bridge. To operate this needs to interact with a ths
- special McMAL DMA controller, and sometimes an RGMII or ZMII
- interface. In addition to the nodes and properties described
- below, the node for the OPB bus on which the EMAC sits must have a
- correct clock-frequency property.
-
- i) The EMAC node itself
-
- Required properties:
- - device_type : "network"
-
- - compatible : compatible list, contains 2 entries, first is
- "ibm,emac-CHIP" where CHIP is the host ASIC (440gx,
- 405gp, Axon) and second is either "ibm,emac" or
- "ibm,emac4". For Axon, thus, we have: "ibm,emac-axon",
- "ibm,emac4"
- - interrupts : <interrupt mapping for EMAC IRQ and WOL IRQ>
- - interrupt-parent : optional, if needed for interrupt mapping
- - reg : <registers mapping>

- thresholds).
- For Axon, 0x00000010
- - mal-burst-size : 1 cell, MAL burst size (used to calculate thresholds)
- in bytes.
- For Axon, 0x00000100 (I think ...)
- - phy-mode : string, mode of operations of the PHY interface.

- "tbi", "gmii", rtbi", "sgmii".
- For Axon on CAB, it is "rgmii"
- - mdio-device : 1 cell, required iff using shared MDIO registers
- (440EP). phandle of the EMAC to use to drive the
- MDIO lines for the PHY used by this EMAC.
- - zmii-device : 1 cell, required iff connected to a ZMII. phandle of
- the ZMII device node
- - zmii-channel : 1 cell, required iff connected to a ZMII. Which ZMII
- channel or 0xffffffff if ZMII is only used for MDIO.
- - rgmii-device : 1 cell, required iff connected to an RGMII. phandle
- of the RGMII device node.
- For Axon: phandle of plb5/plb4/opb/rgmii
- - rgmii-channel : 1 cell, required iff connected to an RGMII. Which
- RGMII channel is used by this EMAC.
- Fox Axon: present, whatever value is appropriate for each
- EMAC, that is the content of the current (bogus) "phy-port"
- property.
-
- Optional properties:
- - phy-address : 1 cell, optional, MDIO address of the PHY. If absent,
- a search is performed.
- - phy-map : 1 cell, optional, bitmap of addresses to probe the PHY
- for, used if phy-address is absent. bit 0x00000001 is
- MDIO address 0.
- For Axon it can be absent, though my current driver
- doesn't handle phy-address yet so for now, keep
- 0x00ffffff in it.
- - rx-fifo-size-gige : 1 cell, Rx fifo size in bytes for 1000 Mb/sec
- operations (if absent the value is the same as
- rx-fifo-size). For Axon, either absent or 2048.
- - tx-fifo-size-gige : 1 cell, Tx fifo size in bytes for 1000 Mb/sec
- operations (if absent the value is the same as
- tx-fifo-size). For Axon, either absent or 2048.

- phy-mode = "rmii";
- phy-map = <00000001>;
- zmii-device = <&ZMII0>;
- zmii-channel = <0>;
- };
-
- ii) McMAL node
-
- Required properties:
- - device_type : "dma-controller"
- - compatible : compatible list, containing 2 entries, first is
- "ibm,mcmal-CHIP" where CHIP is the host ASIC (like
- emac) and the second is either "ibm,mcmal" or
- "ibm,mcmal2".
- For Axon, "ibm,mcmal-axon","ibm,mcmal2"
- - interrupts : <interrupt mapping for the MAL interrupts sources:
- 5 sources: tx_eob, rx_eob, serr, txde, rxde>.
- For Axon: This is _different_ from the current
- firmware. We use the "delayed" interrupts for txeob
- and rxeob. Thus we end up with mapping those 5 MPIC
- interrupts, all level positive sensitive: 10, 11, 32,
- 33, 34 (in decimal)

- - dcr-parent : if needed for dcr-reg

-
- iii) ZMII node
-
- Required properties:
- - compatible : compatible list, containing 2 entries, first is
- "ibm,zmii-CHIP" where CHIP is the host ASIC (like
- EMAC) and the second is "ibm,zmii".
- For Axon, there is no ZMII node.
- - reg : <registers mapping>
-
- iv) RGMII node
-
- Required properties:
- - compatible : compatible list, containing 2 entries, first is
- "ibm,rgmii-CHIP" where CHIP is the host ASIC (like
- EMAC) and the second is "ibm,rgmii".
- For Axon, "ibm,rgmii-axon","ibm,rgmii"
- - reg : <registers mapping>
- - revision : as provided by the RGMII new version register if
- available.
- For Axon: 0x0000012a
-
- d) Xilinx IP cores
-
- The Xilinx EDK toolchain ships with a set of IP cores (devices) for use
- in Xilinx Spartan and Virtex FPGAs. The devices cover the whole range
- of standard device types (network, serial, etc.) and miscellaneous
- devices (gpio, LCD, spi, etc). Also, since these devices are
- implemented within the fpga fabric every instance of the device can be
- synthesised with different options that change the behaviour.
-
- Each IP-core has a set of parameters which the FPGA designer can use to
- control how the core is synthesized. Historically, the EDK tool would
- extract the device parameters relevant to device drivers and copy them
- into an 'xparameters.h' in the form of #define symbols. This tells the
- device drivers how the IP cores are configured, but it requres the kernel
- to be recompiled every time the FPGA bitstream is resynthesized.
-
- The new approach is to export the parameters into the device tree and
- generate a new device tree each time the FPGA bitstream changes. The
- parameters which used to be exported as #defines will now become
- properties of the device node. In general, device nodes for IP-cores
- will take the following form:
-
- (name): (generic-name)@(base-address) {
- compatible = "xlnx,(ip-core-name)-(HW_VER)"
- [, (list of compatible devices), ...];
- reg = <(baseaddr) (size)>;
- interrupt-parent = <&interrupt-controller-phandle>;
- interrupts = < ... >;
- xlnx,(parameter1) = "(string-value)";
- xlnx,(parameter2) = <(int-value)>;
- };
-
- (generic-name): an open firmware-style name that describes the
- generic class of device. Preferably, this is one word, such
- as 'serial' or 'ethernet'.
- (ip-core-name): the name of the ip block (given after the BEGIN
- directive in system.mhs). Should be in lowercase
- and all underscores '_' converted to dashes '-'.
- (name): is derived from the "PARAMETER INSTANCE" value.
- (parameter#): C_* parameters from system.mhs. The C_ prefix is
- dropped from the parameter name, the name is converted
- to lowercase and all underscore '_' characters are
- converted to dashes '-'.
- (baseaddr): the baseaddr parameter value (often named C_BASEADDR).
- (HW_VER): from the HW_VER parameter.
- (size): the address range size (often C_HIGHADDR - C_BASEADDR + 1).
-
- Typically, the compatible list will include the exact IP core version
- followed by an older IP core version which implements the same
- interface or any other device with the same interface.
-
- 'reg', 'interrupt-parent' and 'interrupts' are all optional properties.
-
- For example, the following block from system.mhs:
-
- BEGIN opb_uartlite
- PARAMETER INSTANCE = opb_uartlite_0
- PARAMETER HW_VER = 1.00.b
- PARAMETER C_BAUDRATE = 115200
- PARAMETER C_DATA_BITS = 8
- PARAMETER C_ODD_PARITY = 0
- PARAMETER C_USE_PARITY = 0
- PARAMETER C_CLK_FREQ = 50000000
- PARAMETER C_BASEADDR = 0xEC100000
- PARAMETER C_HIGHADDR = 0xEC10FFFF
- BUS_INTERFACE SOPB = opb_7
- PORT OPB_Clk = CLK_50MHz
- PORT Interrupt = opb_uartlite_0_Interrupt
- PORT RX = opb_uartlite_0_RX
- PORT TX = opb_uartlite_0_TX
- PORT OPB_Rst = sys_bus_reset_0
- END
-
- becomes the following device tree node:
-
- opb_uartlite_0: serial@ec100000 {
- device_type = "serial";
- compatible = "xlnx,opb-uartlite-1.00.b";
- reg = <ec100000 10000>;
- interrupt-parent = <&opb_intc_0>;
- interrupts = <1 0>; // got this from the opb_intc parameters
- current-speed = <d#115200>; // standard serial device prop
- clock-frequency = <d#50000000>; // standard serial device prop
- xlnx,data-bits = <8>;
- xlnx,odd-parity = <0>;
- xlnx,use-parity = <0>;
- };
-
- Some IP cores actually implement 2 or more logical devices. In
- this case, the device should still describe the whole IP core with
- a single node and add a child node for each logical device. The
- ranges property can be used to translate from parent IP-core to the
- registers of each device. In addition, the parent node should be
- compatible with the bus type 'xlnx,compound', and should contain
- #address-cells and #size-cells, as with any other bus. (Note: this
- makes the assumption that both logical devices have the same bus
- binding. If this is not true, then separate nodes should be used
- for each logical device). The 'cell-index' property can be used to
- enumerate logical devices within an IP core. For example, the
- following is the system.mhs entry for the dual ps2 controller found
- on the ml403 reference design.
-
- BEGIN opb_ps2_dual_ref
- PARAMETER INSTANCE = opb_ps2_dual_ref_0
- PARAMETER HW_VER = 1.00.a
- PARAMETER C_BASEADDR = 0xA9000000
- PARAMETER C_HIGHADDR = 0xA9001FFF
- BUS_INTERFACE SOPB = opb_v20_0
- PORT Sys_Intr1 = ps2_1_intr
- PORT Sys_Intr2 = ps2_2_intr
- PORT Clkin1 = ps2_clk_rx_1
- PORT Clkin2 = ps2_clk_rx_2
- PORT Clkpd1 = ps2_clk_tx_1
- PORT Clkpd2 = ps2_clk_tx_2
- PORT Rx1 = ps2_d_rx_1
- PORT Rx2 = ps2_d_rx_2
- PORT Txpd1 = ps2_d_tx_1
- PORT Txpd2 = ps2_d_tx_2
- END
-
- It would result in the following device tree nodes:
-
- opb_ps2_dual_ref_0: opb-ps2-dual-ref@a9000000 {
- #address-cells = <1>;
- #size-cells = <1>;
- compatible = "xlnx,compound";
- ranges = <0 a9000000 2000>;
- // If this device had extra parameters, then they would
- // go here.
- ps2@0 {
- compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
- reg = <0 40>;
- interrupt-parent = <&opb_intc_0>;
- interrupts = <3 0>;
- cell-index = <0>;

- Also, the system.mhs file defines bus attachments from the processor
- to the devices. The device tree structure should reflect the bus
- attachments. Again an example; this system.mhs fragment:

- Gives this device tree (some properties removed for clarity):
-
- plb@0 {
- #address-cells = <1>;
- #size-cells = <1>;
- compatible = "xlnx,plb-v34-1.02.a";
- device_type = "ibm,plb";

- #address-cells = <1>;
- #size-cells = <1>;
- ranges = <20000000 20000000 20000000
- 60000000 60000000 20000000

- };
-
- opb_intc_0: interrupt-controller@d1000fc0 {
- reg = <d1000fc0 20>;
- };
- };
- };
-
- That covers the general approach to binding xilinx IP cores into the
- device tree. The following are bindings for specific devices:
-
- i) Xilinx ML300 Framebuffer
-
- Simple framebuffer device from the ML300 reference design (also on the
- ML403 reference design as well as others).
-
- Optional properties:
- - resolution = <xres yres> : pixel resolution of framebuffer. Some
- implementations use a different resolution.
- Default is <d#640 d#480>
- - virt-resolution = <xvirt yvirt> : Size of framebuffer in memory.
- Default is <d#1024 d#480>.
- - rotate-display (empty) : rotate display 180 degrees.
-
- ii) Xilinx SystemACE
-
- The Xilinx SystemACE device is used to program FPGAs from an FPGA
- bitstream stored on a CF card. It can also be used as a generic CF
- interface device.
-
- Optional properties:
- - 8-bit (empty) : Set this property for SystemACE in 8 bit mode
-
- iii) Xilinx EMAC and Xilinx TEMAC
-
- Xilinx Ethernet devices. In addition to general xilinx properties
- listed above, nodes for these devices should include a phy-handle
- property, and may include other common network device properties
- like local-mac-address.
-
- iv) Xilinx Uartlite
-
- Xilinx uartlite devices are simple fixed speed serial ports.
-
- Required properties:
- - current-speed : Baud rate of uartlite
-
- v) Xilinx hwicap
-
- Xilinx hwicap devices provide access to the configuration logic
- of the FPGA through the Internal Configuration Access Port
- (ICAP). The ICAP enables partial reconfiguration of the FPGA,
- readback of the configuration information, and some control over
- 'warm boots' of the FPGA fabric.
-
- Required properties:
- - xlnx,family : The family of the FPGA, necessary since the
- capabilities of the underlying ICAP hardware
- differ between different families. May be
- 'virtex2p', 'virtex4', or 'virtex5'.
-
- vi) Xilinx Uart 16550
-
- Xilinx UART 16550 devices are very similar to the NS16550 but with
- different register spacing and an offset from the base address.
-
- Required properties:
- - clock-frequency : Frequency of the clock input
- - reg-offset : A value of 3 is required
- - reg-shift : A value of 2 is required
-
- e) USB EHCI controllers
-
- Required properties:
- - compatible : should be "usb-ehci".
- - reg : should contain at least address and length of the standard EHCI
- register set for the device. Optional platform-dependent registers
- (debug-port or other) can be also specified here, but only after
- definition of standard EHCI registers.
- - interrupts : one EHCI interrupt should be described here.
- If device registers are implemented in big endian mode, the device
- node should have "big-endian-regs" property.
- If controller implementation operates with big endian descriptors,
- "big-endian-desc" property should be specified.
- If both big endian registers and descriptors are used by the controller
- implementation, "big-endian" property can be specified instead of having
- both "big-endian-regs" and "big-endian-desc".
-
- Example (Sequoia 440EPx):
- ehci@e0000300 {
- compatible = "ibm,usb-ehci-440epx", "usb-ehci";
- interrupt-parent = <&UIC0>;
- interrupts = <1a 4>;
- reg = <0 e0000300 90 0 e0000390 70>;
- big-endian;
- };
-
- f) MDIO on GPIOs
-
- Currently defined compatibles:
- - virtual,gpio-mdio
-
- MDC and MDIO lines connected to GPIO controllers are listed in the
- gpios property as described in section VIII.1 in the following order:
-
- MDC, MDIO.
-
- Example:
-
- mdio {
- compatible = "virtual,mdio-gpio";
- #address-cells = <1>;
- #size-cells = <0>;
- gpios = <&qe_pio_a 11
- &qe_pio_c 6>;
- };
-
- g) SPI (Serial Peripheral Interface) busses
-
- SPI busses can be described with a node for the SPI master device
- and a set of child nodes for each SPI slave on the bus. For this
- discussion, it is assumed that the system's SPI controller is in
- SPI master mode. This binding does not describe SPI controllers
- in slave mode.
-
- The SPI master node requires the following properties:
- - #address-cells - number of cells required to define a chip select
- address on the SPI bus.
- - #size-cells - should be zero.
- - compatible - name of SPI bus controller following generic names
- recommended practice.
- No other properties are required in the SPI bus node. It is assumed
- that a driver for an SPI bus device will understand that it is an SPI bus.
- However, the binding does not attempt to define the specific method for
- assigning chip select numbers. Since SPI chip select configuration is
- flexible and non-standardized, it is left out of this binding with the
- assumption that board specific platform code will be used to manage
- chip selects. Individual drivers can define additional properties to
- support describing the chip select layout.
-
- SPI slave nodes must be children of the SPI master node and can
- contain the following properties.
- - reg - (required) chip select address of device.
- - compatible - (required) name of SPI device following generic names
- recommended practice
- - spi-max-frequency - (required) Maximum SPI clocking speed of device in Hz
- - spi-cpol - (optional) Empty property indicating device requires
- inverse clock polarity (CPOL) mode
- - spi-cpha - (optional) Empty property indicating device requires
- shifted clock phase (CPHA) mode
- - spi-cs-high - (optional) Empty property indicating device requires
- chip select active high
-
- SPI example for an MPC5200 SPI bus:
- spi@f00 {
- #address-cells = <1>;
- #size-cells = <0>;
- compatible = "fsl,mpc5200b-spi","fsl,mpc5200-spi";
- reg = <0xf00 0x20>;
- interrupts = <2 13 0 2 14 0>;
- interrupt-parent = <&mpc5200_pic>;
-
- ethernet-switch@0 {
- compatible = "micrel,ks8995m";
- spi-max-frequency = <1000000>;
- reg = <0>;
- };
-
- codec@1 {
- compatible = "ti,tlv320aic26";
- spi-max-frequency = <100000>;
- reg = <1>;
- };
- };

-VII - Marvell Discovery mv64[345]6x System Controller chips
-===========================================================
-
-The Marvell mv64[345]60 series of system controller chips contain
-many of the peripherals needed to implement a complete computer
-system. In this section, we define device tree nodes to describe
-the system controller chip itself and each of the peripherals
-which it contains. Compatible string values for each node are
-prefixed with the string "marvell,", for Marvell Technology Group Ltd.
-
-1) The /system-controller node
-
- This node is used to represent the system-controller and must be
- present when the system uses a system controller chip. The top-level
- system-controller node contains information that is global to all
- devices within the system controller chip. The node name begins
- with "system-controller" followed by the unit address, which is
- the base address of the memory-mapped register set for the system
- controller chip.
-
- Required properties:
-
- - ranges : Describes the translation of system controller addresses
- for memory mapped registers.
- - clock-frequency: Contains the main clock frequency for the system
- controller chip.
- - reg : This property defines the address and size of the
- memory-mapped registers contained within the system controller
- chip. The address specified in the "reg" property should match
- the unit address of the system-controller node.
- - #address-cells : Address representation for system controller
- devices. This field represents the number of cells needed to
- represent the address of the memory-mapped registers of devices
- within the system controller chip.
- - #size-cells : Size representation for for the memory-mapped
- registers within the system controller chip.
- - #interrupt-cells : Defines the width of cells used to represent
- interrupts.
-
- Optional properties:
-
- - model : The specific model of the system controller chip. Such
- as, "mv64360", "mv64460", or "mv64560".
- - compatible : A string identifying the compatibility identifiers
- of the system controller chip.
-
- The system-controller node contains child nodes for each system
- controller device that the platform uses. Nodes should not be created
- for devices which exist on the system controller chip but are not used
-
- Example Marvell Discovery mv64360 system-controller node:
-
- system-controller@f1000000 { /* Marvell Discovery mv64360 */
- #address-cells = <1>;
- #size-cells = <1>;
- model = "mv64360"; /* Default */
- compatible = "marvell,mv64360";
- clock-frequency = <133333333>;
- reg = <0xf1000000 0x10000>;
- virtual-reg = <0xf1000000>;
- ranges = <0x88000000 0x88000000 0x1000000 /* PCI 0 I/O Space */
- 0x80000000 0x80000000 0x8000000 /* PCI 0 MEM Space */
- 0xa0000000 0xa0000000 0x4000000 /* User FLASH */

-
- [ child node definitions... ]
- }
-
-2) Child nodes of /system-controller
-
- a) Marvell Discovery MDIO bus
-
- The MDIO is a bus to which the PHY devices are connected. For each

-
- b) Marvell Discovery ethernet controller
-
- The Discover ethernet controller is described with two levels
- of nodes. The first level describes an ethernet silicon block
- and the second level describes up to 3 ethernet nodes within
- that block. The reason for the multiple levels is that the
- registers for the node are interleaved within a single set
- of registers. The "ethernet-block" level describes the
- shared register set, and the "ethernet" nodes describe ethernet
- port-specific properties.

+ 4xx/Axon EMAC ethernet nodes
+
+ The EMAC ethernet controller in IBM and AMCC 4xx chips, and also

+Marvell Discovery mv64[345]6x System Controller chips
+===========================================================
+
+The Marvell mv64[345]60 series of system controller chips contain
+many of the peripherals needed to implement a complete computer
+system. In this section, we define device tree nodes to describe
+the system controller chip itself and each of the peripherals
+which it contains. Compatible string values for each node are
+prefixed with the string "marvell,", for Marvell Technology Group Ltd.
+
+1) The /system-controller node
+
+ This node is used to represent the system-controller and must be
+ present when the system uses a system controller chip. The top-level
+ system-controller node contains information that is global to all
+ devices within the system controller chip. The node name begins
+ with "system-controller" followed by the unit address, which is
+ the base address of the memory-mapped register set for the system
+ controller chip.
+
+ Required properties:
+
+ - ranges : Describes the translation of system controller addresses
+ for memory mapped registers.
+ - clock-frequency: Contains the main clock frequency for the system
+ controller chip.
+ - reg : This property defines the address and size of the
+ memory-mapped registers contained within the system controller
+ chip. The address specified in the "reg" property should match
+ the unit address of the system-controller node.
+ - #address-cells : Address representation for system controller
+ devices. This field represents the number of cells needed to
+ represent the address of the memory-mapped registers of devices
+ within the system controller chip.
+ - #size-cells : Size representation for for the memory-mapped
+ registers within the system controller chip.
+ - #interrupt-cells : Defines the width of cells used to represent
+ interrupts.
+
+ Optional properties:
+
+ - model : The specific model of the system controller chip. Such
+ as, "mv64360", "mv64460", or "mv64560".
+ - compatible : A string identifying the compatibility identifiers
+ of the system controller chip.
+
+ The system-controller node contains child nodes for each system
+ controller device that the platform uses. Nodes should not be created
+ for devices which exist on the system controller chip but are not used
+
+ Example Marvell Discovery mv64360 system-controller node:
+
+ system-controller@f1000000 { /* Marvell Discovery mv64360 */
+ #address-cells = <1>;
+ #size-cells = <1>;
+ model = "mv64360"; /* Default */
+ compatible = "marvell,mv64360";
+ clock-frequency = <133333333>;
+ reg = <0xf1000000 0x10000>;
+ virtual-reg = <0xf1000000>;
+ ranges = <0x88000000 0x88000000 0x1000000 /* PCI 0 I/O Space */
+ 0x80000000 0x80000000 0x8000000 /* PCI 0 MEM Space */
+ 0xa0000000 0xa0000000 0x4000000 /* User FLASH */

+
+ [ child node definitions... ]
+ }
+
+2) Child nodes of /system-controller
+
+ a) Marvell Discovery MDIO bus
+
+ The MDIO is a bus to which the PHY devices are connected. For each
+ device that exists on this bus, a child node should be created. See
+ the definition of the PHY node below for an example of how to define
+ a PHY.

+
+
+ b) Marvell Discovery ethernet controller
+
+ The Discover ethernet controller is described with two levels
+ of nodes. The first level describes an ethernet silicon block
+ and the second level describes up to 3 ethernet nodes within
+ that block. The reason for the multiple levels is that the
+ registers for the node are interleaved within a single set
+ of registers. The "ethernet-block" level describes the
+ shared register set, and the "ethernet" nodes describe ethernet
+ port-specific properties.

--- /dev/null
+SPI (Serial Peripheral Interface) busses
+
+SPI busses can be described with a node for the SPI master device
+and a set of child nodes for each SPI slave on the bus. For this
+discussion, it is assumed that the system's SPI controller is in
+SPI master mode. This binding does not describe SPI controllers
+in slave mode.
+
+The SPI master node requires the following properties:
+- #address-cells - number of cells required to define a chip select
+ address on the SPI bus.
+- #size-cells - should be zero.
+- compatible - name of SPI bus controller following generic names
+ recommended practice.
+No other properties are required in the SPI bus node. It is assumed
+that a driver for an SPI bus device will understand that it is an SPI bus.
+However, the binding does not attempt to define the specific method for
+assigning chip select numbers. Since SPI chip select configuration is
+flexible and non-standardized, it is left out of this binding with the
+assumption that board specific platform code will be used to manage
+chip selects. Individual drivers can define additional properties to
+support describing the chip select layout.
+
+SPI slave nodes must be children of the SPI master node and can
+contain the following properties.
+- reg - (required) chip select address of device.
+- compatible - (required) name of SPI device following generic names
+ recommended practice
+- spi-max-frequency - (required) Maximum SPI clocking speed of device in Hz
+- spi-cpol - (optional) Empty property indicating device requires
+ inverse clock polarity (CPOL) mode
+- spi-cpha - (optional) Empty property indicating device requires
+ shifted clock phase (CPHA) mode
+- spi-cs-high - (optional) Empty property indicating device requires
+ chip select active high
+
+SPI example for an MPC5200 SPI bus:
+ spi@f00 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "fsl,mpc5200b-spi","fsl,mpc5200-spi";
+ reg = <0xf00 0x20>;
+ interrupts = <2 13 0 2 14 0>;
+ interrupt-parent = <&mpc5200_pic>;
+
+ ethernet-switch@0 {
+ compatible = "micrel,ks8995m";
+ spi-max-frequency = <1000000>;
+ reg = <0>;
+ };
+
+ codec@1 {
+ compatible = "ti,tlv320aic26";
+ spi-max-frequency = <100000>;
+ reg = <1>;
+ };
+ };
--- /dev/null
+USB EHCI controllers
+
+Required properties:
+ - compatible : should be "usb-ehci".
+ - reg : should contain at least address and length of the standard EHCI
+ register set for the device. Optional platform-dependent registers
+ (debug-port or other) can be also specified here, but only after
+ definition of standard EHCI registers.
+ - interrupts : one EHCI interrupt should be described here.
+If device registers are implemented in big endian mode, the device
+node should have "big-endian-regs" property.
+If controller implementation operates with big endian descriptors,
+"big-endian-desc" property should be specified.
+If both big endian registers and descriptors are used by the controller
+implementation, "big-endian" property can be specified instead of having
+both "big-endian-regs" and "big-endian-desc".
+
+Example (Sequoia 440EPx):
+ ehci@e0000300 {
+ compatible = "ibm,usb-ehci-440epx", "usb-ehci";
+ interrupt-parent = <&UIC0>;
+ interrupts = <1a 4>;
+ reg = <0 e0000300 90 0 e0000390 70>;
+ big-endian;
+ };
--- /dev/null
+ d) Xilinx IP cores
+
+ The Xilinx EDK toolchain ships with a set of IP cores (devices) for use
+ in Xilinx Spartan and Virtex FPGAs. The devices cover the whole range
+ of standard device types (network, serial, etc.) and miscellaneous
+ devices (gpio, LCD, spi, etc). Also, since these devices are
+ implemented within the fpga fabric every instance of the device can be
+ synthesised with different options that change the behaviour.
+
+ Each IP-core has a set of parameters which the FPGA designer can use to
+ control how the core is synthesized. Historically, the EDK tool would
+ extract the device parameters relevant to device drivers and copy them
+ into an 'xparameters.h' in the form of #define symbols. This tells the
+ device drivers how the IP cores are configured, but it requres the kernel
+ to be recompiled every time the FPGA bitstream is resynthesized.
+
+ The new approach is to export the parameters into the device tree and
+ generate a new device tree each time the FPGA bitstream changes. The
+ parameters which used to be exported as #defines will now become
+ properties of the device node. In general, device nodes for IP-cores
+ will take the following form:
+
+ (name): (generic-name)@(base-address) {
+ compatible = "xlnx,(ip-core-name)-(HW_VER)"
+ [, (list of compatible devices), ...];
+ reg = <(baseaddr) (size)>;
+ interrupt-parent = <&interrupt-controller-phandle>;
+ interrupts = < ... >;
+ xlnx,(parameter1) = "(string-value)";
+ xlnx,(parameter2) = <(int-value)>;
+ };
+
+ (generic-name): an open firmware-style name that describes the
+ generic class of device. Preferably, this is one word, such
+ as 'serial' or 'ethernet'.
+ (ip-core-name): the name of the ip block (given after the BEGIN
+ directive in system.mhs). Should be in lowercase
+ and all underscores '_' converted to dashes '-'.
+ (name): is derived from the "PARAMETER INSTANCE" value.
+ (parameter#): C_* parameters from system.mhs. The C_ prefix is
+ dropped from the parameter name, the name is converted
+ to lowercase and all underscore '_' characters are
+ converted to dashes '-'.
+ (baseaddr): the baseaddr parameter value (often named C_BASEADDR).
+ (HW_VER): from the HW_VER parameter.
+ (size): the address range size (often C_HIGHADDR - C_BASEADDR + 1).
+
+ Typically, the compatible list will include the exact IP core version
+ followed by an older IP core version which implements the same
+ interface or any other device with the same interface.
+
+ 'reg', 'interrupt-parent' and 'interrupts' are all optional properties.
+
+ For example, the following block from system.mhs:
+
+ BEGIN opb_uartlite
+ PARAMETER INSTANCE = opb_uartlite_0
+ PARAMETER HW_VER = 1.00.b
+ PARAMETER C_BAUDRATE = 115200
+ PARAMETER C_DATA_BITS = 8
+ PARAMETER C_ODD_PARITY = 0
+ PARAMETER C_USE_PARITY = 0
+ PARAMETER C_CLK_FREQ = 50000000
+ PARAMETER C_BASEADDR = 0xEC100000
+ PARAMETER C_HIGHADDR = 0xEC10FFFF
+ BUS_INTERFACE SOPB = opb_7
+ PORT OPB_Clk = CLK_50MHz
+ PORT Interrupt = opb_uartlite_0_Interrupt
+ PORT RX = opb_uartlite_0_RX
+ PORT TX = opb_uartlite_0_TX
+ PORT OPB_Rst = sys_bus_reset_0
+ END
+
+ becomes the following device tree node:
+
+ opb_uartlite_0: serial@ec100000 {
+ device_type = "serial";
+ compatible = "xlnx,opb-uartlite-1.00.b";
+ reg = <ec100000 10000>;
+ interrupt-parent = <&opb_intc_0>;
+ interrupts = <1 0>; // got this from the opb_intc parameters
+ current-speed = <d#115200>; // standard serial device prop
+ clock-frequency = <d#50000000>; // standard serial device prop
+ xlnx,data-bits = <8>;
+ xlnx,odd-parity = <0>;
+ xlnx,use-parity = <0>;
+ };
+
+ Some IP cores actually implement 2 or more logical devices. In
+ this case, the device should still describe the whole IP core with
+ a single node and add a child node for each logical device. The
+ ranges property can be used to translate from parent IP-core to the
+ registers of each device. In addition, the parent node should be
+ compatible with the bus type 'xlnx,compound', and should contain
+ #address-cells and #size-cells, as with any other bus. (Note: this
+ makes the assumption that both logical devices have the same bus
+ binding. If this is not true, then separate nodes should be used
+ for each logical device). The 'cell-index' property can be used to
+ enumerate logical devices within an IP core. For example, the
+ following is the system.mhs entry for the dual ps2 controller found
+ on the ml403 reference design.
+
+ BEGIN opb_ps2_dual_ref
+ PARAMETER INSTANCE = opb_ps2_dual_ref_0
+ PARAMETER HW_VER = 1.00.a
+ PARAMETER C_BASEADDR = 0xA9000000
+ PARAMETER C_HIGHADDR = 0xA9001FFF
+ BUS_INTERFACE SOPB = opb_v20_0
+ PORT Sys_Intr1 = ps2_1_intr
+ PORT Sys_Intr2 = ps2_2_intr
+ PORT Clkin1 = ps2_clk_rx_1
+ PORT Clkin2 = ps2_clk_rx_2
+ PORT Clkpd1 = ps2_clk_tx_1
+ PORT Clkpd2 = ps2_clk_tx_2
+ PORT Rx1 = ps2_d_rx_1
+ PORT Rx2 = ps2_d_rx_2
+ PORT Txpd1 = ps2_d_tx_1
+ PORT Txpd2 = ps2_d_tx_2
+ END
+
+ It would result in the following device tree nodes:
+
+ opb_ps2_dual_ref_0: opb-ps2-dual-ref@a9000000 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "xlnx,compound";
+ ranges = <0 a9000000 2000>;
+ // If this device had extra parameters, then they would
+ // go here.
+ ps2@0 {
+ compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
+ reg = <0 40>;
+ interrupt-parent = <&opb_intc_0>;
+ interrupts = <3 0>;
+ cell-index = <0>;
+ };
+ ps2@1000 {
+ compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
+ reg = <1000 40>;
+ interrupt-parent = <&opb_intc_0>;
+ interrupts = <3 0>;
+ cell-index = <0>;
+ };
+ };
+
+ Also, the system.mhs file defines bus attachments from the processor
+ to the devices. The device tree structure should reflect the bus
+ attachments. Again an example; this system.mhs fragment:
+
+ BEGIN ppc405_virtex4
+ PARAMETER INSTANCE = ppc405_0
+ PARAMETER HW_VER = 1.01.a
+ BUS_INTERFACE DPLB = plb_v34_0
+ BUS_INTERFACE IPLB = plb_v34_0
+ END
+
+ BEGIN opb_intc
+ PARAMETER INSTANCE = opb_intc_0
+ PARAMETER HW_VER = 1.00.c
+ PARAMETER C_BASEADDR = 0xD1000FC0
+ PARAMETER C_HIGHADDR = 0xD1000FDF
+ BUS_INTERFACE SOPB = opb_v20_0
+ END
+
+ BEGIN opb_uart16550
+ PARAMETER INSTANCE = opb_uart16550_0
+ PARAMETER HW_VER = 1.00.d
+ PARAMETER C_BASEADDR = 0xa0000000
+ PARAMETER C_HIGHADDR = 0xa0001FFF
+ BUS_INTERFACE SOPB = opb_v20_0
+ END
+
+ BEGIN plb_v34
+ PARAMETER INSTANCE = plb_v34_0
+ PARAMETER HW_VER = 1.02.a
+ END
+
+ BEGIN plb_bram_if_cntlr
+ PARAMETER INSTANCE = plb_bram_if_cntlr_0
+ PARAMETER HW_VER = 1.00.b
+ PARAMETER C_BASEADDR = 0xFFFF0000
+ PARAMETER C_HIGHADDR = 0xFFFFFFFF
+ BUS_INTERFACE SPLB = plb_v34_0
+ END
+
+ BEGIN plb2opb_bridge
+ PARAMETER INSTANCE = plb2opb_bridge_0
+ PARAMETER HW_VER = 1.01.a
+ PARAMETER C_RNG0_BASEADDR = 0x20000000
+ PARAMETER C_RNG0_HIGHADDR = 0x3FFFFFFF
+ PARAMETER C_RNG1_BASEADDR = 0x60000000
+ PARAMETER C_RNG1_HIGHADDR = 0x7FFFFFFF
+ PARAMETER C_RNG2_BASEADDR = 0x80000000
+ PARAMETER C_RNG2_HIGHADDR = 0xBFFFFFFF
+ PARAMETER C_RNG3_BASEADDR = 0xC0000000
+ PARAMETER C_RNG3_HIGHADDR = 0xDFFFFFFF
+ BUS_INTERFACE SPLB = plb_v34_0
+ BUS_INTERFACE MOPB = opb_v20_0
+ END
+
+ Gives this device tree (some properties removed for clarity):
+
+ plb@0 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "xlnx,plb-v34-1.02.a";
+ device_type = "ibm,plb";
+ ranges; // 1:1 translation
+
+ plb_bram_if_cntrl_0: bram@ffff0000 {
+ reg = <ffff0000 10000>;
+ }
+
+ opb@20000000 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <20000000 20000000 20000000
+ 60000000 60000000 20000000
+ 80000000 80000000 40000000
+ c0000000 c0000000 20000000>;

+
+ opb_intc_0: interrupt-controller@d1000fc0 {

+ };
+ };
+ };
+
+ That covers the general approach to binding xilinx IP cores into the
+ device tree. The following are bindings for specific devices:
+
+ i) Xilinx ML300 Framebuffer
+
+ Simple framebuffer device from the ML300 reference design (also on the
+ ML403 reference design as well as others).
+
+ Optional properties:
+ - resolution = <xres yres> : pixel resolution of framebuffer. Some
+ implementations use a different resolution.
+ Default is <d#640 d#480>
+ - virt-resolution = <xvirt yvirt> : Size of framebuffer in memory.
+ Default is <d#1024 d#480>.
+ - rotate-display (empty) : rotate display 180 degrees.
+
+ ii) Xilinx SystemACE
+
+ The Xilinx SystemACE device is used to program FPGAs from an FPGA
+ bitstream stored on a CF card. It can also be used as a generic CF
+ interface device.
+
+ Optional properties:
+ - 8-bit (empty) : Set this property for SystemACE in 8 bit mode
+
+ iii) Xilinx EMAC and Xilinx TEMAC
+
+ Xilinx Ethernet devices. In addition to general xilinx properties
+ listed above, nodes for these devices should include a phy-handle
+ property, and may include other common network device properties
+ like local-mac-address.
+
+ iv) Xilinx Uartlite
+
+ Xilinx uartlite devices are simple fixed speed serial ports.
+
+ Required properties:
+ - current-speed : Baud rate of uartlite
+
+ v) Xilinx hwicap
+
+ Xilinx hwicap devices provide access to the configuration logic
+ of the FPGA through the Internal Configuration Access Port
+ (ICAP). The ICAP enables partial reconfiguration of the FPGA,
+ readback of the configuration information, and some control over
+ 'warm boots' of the FPGA fabric.
+
+ Required properties:
+ - xlnx,family : The family of the FPGA, necessary since the
+ capabilities of the underlying ICAP hardware
+ differ between different families. May be
+ 'virtex2p', 'virtex4', or 'virtex5'.
+
+ vi) Xilinx Uart 16550
+
+ Xilinx UART 16550 devices are very similar to the NS16550 but with
+ different register spacing and an offset from the base address.
+
+ Required properties:
+ - clock-frequency : Frequency of the clock input
+ - reg-offset : A value of 3 is required
+ - reg-shift : A value of 2 is required

Commentary by Joerg Pommnitz <joerg@raleigh.ibm.com>
-When a process runs in kernel mode, it often has to access user
-mode memory whose address has been passed by an untrusted program.

amount of time.

How does this work?

Where does fixup point to?
-Since we jump to the contents of fixup, fixup obviously points
-to executable code. This code is hidden inside the user access macros.

- * INET An implementation of the TCP/IP protocol suite for the LINUX

- *
- * IP/TCP/UDP checksumming routines
- *
- * Authors: Jorge Cwik, <jorge@laser.satlink.net>
- * Arnt Gulbrandsen, <agulbra@nvg.unit.no>
- * Tom May, <ftom@netcom.com>
- * Andreas Schwab, <schwab@issan.informatik.uni-dortmund.de>
- * Lots of code moved from tcp.c and ip.c; see those files
- * for more names.
- *
- * 03/02/96 Jes Sorensen, Andreas Schwab, Roman Hodek:
- * Fixed some nasty bugs, causing some horrible crashes.
- * A: At some points, the sum (%0) was used as
- * length-counter instead of the length counter
- * (%1). Thanks to Roman Hodek for pointing this out.
- * B: GCC seems to mess up if one uses too many
- * data-registers to hold input values and one tries to
- * specify d0 and d1 as scratch registers. Letting gcc
- * choose these registers itself solves the problem.

+ Instructions for use
+ --------------------
+
+ 1) Map a Linux block device to an existing OSD object.
+
+ In this example, we will use partition id 1234, object id 5678,
+ OSD device /dev/osd1.
+
+ $ echo "1234 5678 /dev/osd1" > /sys/class/osdblk/add
+
+
+ 2) List all active blkdev<->object mappings.
+
+ In this example, we have performed step #1 twice, creating two blkdevs,
+ mapped to two separate OSD objects.
+
+ $ cat /sys/class/osdblk/list
+ 0 174 1234 5678 /dev/osd1
+ 1 179 1994 897123 /dev/osd0
+
+ The columns, in order, are:
+ - blkdev unique id
+ - blkdev assigned major
+ - OSD object partition id
+ - OSD object id
+ - OSD device
+
+
+ 3) Remove an active blkdev<->object mapping.
+
+ In this example, we remove the mapping with blkdev unique id 1.
+
+ $ echo 1 > /sys/class/osdblk/remove
+
+
+ NOTE: The actual creation and deletion of OSD objects is outside the scope
+ of this driver.

+ * intel_update_watermarks - update FIFO watermark values based on current modes

+ * and plane configuration.
+ *
+ * There are several cases to deal with here:
+ * - normal (i.e. non-self-refresh)
+ * - self-refresh (SR) mode
+ * - lines are large relative to FIFO size (buffer can hold up to 2)
+ * - lines are small relative to FIFO size (buffer can hold more than 2
+ * lines), so need to account for TLB latency
+ *
+ * The normal calculation is:
+ * watermark = dotclock * bytes per pixel * latency
+ * where latency is platform & configuration dependent (we assume pessimal
+ * values here).
+ *
+ * The SR calculation is:
+ * watermark = (trunc(latency/line time)+1) * surface width *
+ * bytes per pixel
+ * where
+ * line time = htotal / dotclock
+ * and latency is assumed to be high, as above.
+ *
+ * The final value programmed to the register should always be rounded up,
+ * and include an extra 2 entries to account for clock crossings.
+ *
+ * We don't use the sprite, so we can ignore that. And on Crestline we have
+ * to set the non-SR watermarks to 8.

+ * as a led controller.
+ *
+ * The DIM modes are used to set _blink_ patterns for leds, the pattern is
+ * specified supplying two parameters:
+ * - period: from 0s to 1.6s
+ * - duty cycle: percentage of the period the led is on, from 0 to 100
+ *
+ * LP3944 can be found on Motorola A910 smartphone, where it drives the rgb
+ * leds, the camera flash light and the displays backlights.

- * This function makes sure PEB @pnum is empty, which means it contains only

- * negative error code in case of failure.
- *
- * Empty PEBs have the EC header, and do not have the VID header. The caller of
- * this function should have already made sure the PEB does not have the VID
- * header. However, this function re-checks that, because it is possible that
- * the header and data has already been written to the PEB.
- *
- * Let's consider a possible scenario. Suppose there are 2 tasks - A and B.
- * Task A is in 'wear_leveling_worker()'. It is reading VID header of PEB X to
- * find which LEB it corresponds to. PEB X is currently unmapped, and has no
- * VID header. Task B is trying to write to PEB X.
- *
- * Task A: in 'ubi_io_read_vid_hdr()': reads the VID header from PEB X. The
- * read data contain all 0xFF bytes;
- * Task B: writes VID header and some data to PEB X;
- * Task A: assumes PEB X is empty, calls 'paranoid_check_empty()'. And if we
- * do not re-read the VID header, and do not cancel the checking if it
- * is there, we fail.

- To use rbtrees you'll have to implement your own insert and search cores.
- This will avoid us to use callbacks and to drop drammatically performances.
- I know it's not the cleaner way, but in C (not in C++) to get
- performances and genericity...
-
- Some example of insert and search follows here. The search is a plain
- normal search over an ordered tree. The insert instead must be implemented
- int two steps: as first thing the code must insert the element in
- order as a red leaf in the tree, then the support library function
- rb_insert_color() must be called. Such function will do the
- not trivial work to rebalance the rbtree if necessary.
