+ADS1015 (I2C)
+
+This device is a 12-bit A-D converter with 4 inputs.
+
+The inputs can be used single ended or in certain differential combinations.
+
+For configuration all possible combinations are mapped to 8 channels:
+ 0: Voltage over AIN0 and AIN1.
+ 1: Voltage over AIN0 and AIN3.
+ 2: Voltage over AIN1 and AIN3.
+ 3: Voltage over AIN2 and AIN3.
+ 4: Voltage over AIN0 and GND.
+ 5: Voltage over AIN1 and GND.
+ 6: Voltage over AIN2 and GND.
+ 7: Voltage over AIN3 and GND.
+
+Each channel can be configured individually:
+ - pga is the programmable gain amplifier (values are full scale)
+ 0: +/- 6.144 V
+ 1: +/- 4.096 V
+ 2: +/- 2.048 V (default)
+ 3: +/- 1.024 V
+ 4: +/- 0.512 V
+ 5: +/- 0.256 V
+ - data_rate in samples per second
+ 0: 128
+ 1: 250
+ 2: 490
+ 3: 920
+ 4: 1600 (default)
+ 5: 2400
+ 6: 3300
+
+1) The /ads1015 node
+
+ Required properties:
+
+ - compatible : must be "ti,ads1015"
+ - reg : I2C bus address of the device
+ - #address-cells : must be <1>
+ - #size-cells : must be <0>
+
+ The node contains child nodes for each channel that the platform uses.
+
+ Example ADS1015 node:
+
+ ads1015@49 {
+ compatible = "ti,ads1015";
+ reg = <0x49>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ [ child node definitions... ]
+ }
+
+2) channel nodes
+
+ Required properties:
+
+ - reg : the channel number
+
+ Optional properties:
+
+ - ti,gain : the programmable gain amplifier setting
+ - ti,datarate : the converter data rate
+
+ Example ADS1015 channel node:
+
+ channel@4 {
+ reg = <4>;
+ ti,gain = <3>;
+ ti,datarate = <5>;
+ };

+* Open PIC Binding
+
+This binding specifies what properties must be available in the device tree
+representation of an Open PIC compliant interrupt controller. This binding is
+based on the binding defined for Open PIC in [1] and is a superset of that
+binding.
+
+Required properties:
+
+ NOTE: Many of these descriptions were paraphrased here from [1] to aid
+ readability.
+
+ - compatible: Specifies the compatibility list for the PIC. The type
+ shall be <string> and the value shall include "open-pic".
+
+ - reg: Specifies the base physical address(s) and size(s) of this
+ PIC's addressable register space. The type shall be <prop-encoded-array>.
+
+ - interrupt-controller: The presence of this property identifies the node
+ as an Open PIC. No property value shall be defined.
+
+ - #interrupt-cells: Specifies the number of cells needed to encode an
+ interrupt source. The type shall be a <u32> and the value shall be 2.
+
+ - #address-cells: Specifies the number of cells needed to encode an
+ address. The type shall be <u32> and the value shall be 0. As such,
+ 'interrupt-map' nodes do not have to specify a parent unit address.
+
+Optional properties:
+
+ - pic-no-reset: The presence of this property indicates that the PIC
+ shall not be reset during runtime initialization. No property value shall
+ be defined. The presence of this property also mandates that any
+ initialization related to interrupt sources shall be limited to sources
+ explicitly referenced in the device tree.
+
+* Interrupt Specifier Definition
+
+ Interrupt specifiers consists of 2 cells encoded as
+ follows:
+
+ - <1st-cell>: The interrupt-number that identifies the interrupt source.
+
+ - <2nd-cell>: The level-sense information, encoded as follows:
+ 0 = low-to-high edge triggered
+ 1 = active low level-sensitive
+ 2 = active high level-sensitive
+ 3 = high-to-low edge triggered
+
+* Examples
+
+Example 1:
+
+ /*
+ * An Open PIC interrupt controller
+ */
+ mpic: pic@40000 {
+ // This is an interrupt controller node.
+ interrupt-controller;
+
+ // No address cells so that 'interrupt-map' nodes which reference
+ // this Open PIC node do not need a parent address specifier.
+ #address-cells = <0>;
+
+ // Two cells to encode interrupt sources.
+ #interrupt-cells = <2>;
+
+ // Offset address of 0x40000 and size of 0x40000.
+ reg = <0x40000 0x40000>;
+
+ // Compatible with Open PIC.
+ compatible = "open-pic";
+
+ // The PIC shall not be reset.
+ pic-no-reset;
+ };
+
+Example 2:
+
+ /*
+ * An interrupt generating device that is wired to an Open PIC.
+ */
+ serial0: serial@4500 {
+ // Interrupt source '42' that is active high level-sensitive.
+ // Note that there are only two cells as specified in the interrupt
+ // parent's '#interrupt-cells' property.
+ interrupts = <42 2>;
+
+ // The interrupt controller that this device is wired to.
+ interrupt-parent = <&mpic>;
+ };

+Kernel driver ads1015
+=====================
+
+Supported chips:
+ * Texas Instruments ADS1015
+ Prefix: 'ads1015'
+ Datasheet: Publicly available at the Texas Instruments website :
+ http://focus.ti.com/lit/ds/symlink/ads1015.pdf
+
+Authors:
+ Dirk Eibach, Guntermann & Drunck GmbH <eibach@gdsys.de>
+
+Description
+-----------
+
+This driver implements support for the Texas Instruments ADS1015.
+
+This device is a 12-bit A-D converter with 4 inputs.
+
+The inputs can be used single ended or in certain differential combinations.
+
+The inputs can be made available by 8 sysfs input files in0_input - in7_input:
+in0: Voltage over AIN0 and AIN1.
+in1: Voltage over AIN0 and AIN3.
+in2: Voltage over AIN1 and AIN3.
+in3: Voltage over AIN2 and AIN3.
+in4: Voltage over AIN0 and GND.
+in5: Voltage over AIN1 and GND.
+in6: Voltage over AIN2 and GND.
+in7: Voltage over AIN3 and GND.
+
+Which inputs are available can be configured using platform data or devicetree.
+
+By default all inputs are exported.
+
+Platform Data
+-------------
+
+In linux/i2c/ads1015.h platform data is defined, channel_data contains
+configuration data for the used input combinations:
+- pga is the programmable gain amplifier (values are full scale)
+ 0: +/- 6.144 V
+ 1: +/- 4.096 V
+ 2: +/- 2.048 V
+ 3: +/- 1.024 V
+ 4: +/- 0.512 V
+ 5: +/- 0.256 V
+- data_rate in samples per second
+ 0: 128
+ 1: 250
+ 2: 490
+ 3: 920
+ 4: 1600
+ 5: 2400
+ 6: 3300
+
+Example:
+struct ads1015_platform_data data = {
+ .channel_data = {
+ [2] = { .enabled = true, .pga = 1, .data_rate = 0 },
+ [4] = { .enabled = true, .pga = 4, .data_rate = 5 },
+ }
+};
+
+In this case only in2_input (FS +/- 4.096 V, 128 SPS) and in4_input
+(FS +/- 0.512 V, 2400 SPS) would be created.
+
+Devicetree

- of HP laptops, which have the "Mobile Data Protection System 3D" or
- "3D DriveGuard" feature. On such systems the driver should load
- automatically (via ACPI alias). The accelerometer might also be found
- in other systems, connected via SPI or I2C. The accelerometer data is
- readable via /sys/devices/platform/lis3lv02d.
-
- This driver also provides an absolute input class device, allowing
- a laptop to act as a pinball machine-esque joystick. It provides also
- a misc device which can be used to detect free-fall. On HP laptops,
- if the led infrastructure is activated, support for a led indicating
- disk protection will be provided as hp::hddprotect. For more
- information on the feature, refer to Documentation/hwmon/lis3lv02d.
-
- This driver can also be built as modules. If so, the core module
- will be called lis3lv02d and a specific module for HP laptops will be
- called hp_accel.

- the awesome power of lis3lv02d.

#
+# BISECT_SKIP = 1 (optional, default 0)
+#
+# If BISECT_TYPE is set to test but the build fails, ktest will
+# simply fail the test and end their. You could use BISECT_REPLAY
+# and BISECT_START to resume after you found a new starting point,
+# or you could set BISECT_SKIP to 1. If BISECT_SKIP is set to 1,
+# when something other than the BISECT_TYPE fails, ktest.pl will

+#
+# BISECT_FILES = <path> (optional, default undefined)
+#
+# To just run the git bisect on a specific path, set BISECT_FILES.
+# For example:

+# BISECT_FILES = arch/x86 kernel/time
+#
+# Will run the bisect with "git bisect start -- arch/x86 kernel/time"

# BISECT_REVERSE = 1 (optional, default 0)
#
# In those strange instances where it was broken forever
# With BISECT_REVERSE = 1, The test will consider failures as
# good, and success as bad.
#
+# BISECT_MANUAL = 1 (optional, default 0)
+#
+# In case there's a problem with automating the bisect for
+# whatever reason. (Can't reboot, want to inspect each iteration)
+# Doing a BISECT_MANUAL will have the test wait for you to
+# tell it if the test passed or failed after each iteration.
+# This is basicall the same as running git bisect yourself
+# but ktest will rebuild and install the kernel for you.
+#
# BISECT_CHECK = 1 (optional, default 0)
#
# Just to be sure the good is good and bad is bad, setting
#
# CONFIG_BISECT is the config that failed to boot
#
+# If BISECT_MANUAL is set, it will pause between iterations.
+# This is useful to use just ktest.pl just for the config bisect.
+# If you set it to build, it will run the bisect and you can
+# control what happens in between iterations. It will ask you if
+# the test succeeded or not and continue the config bisect.
+#
# Example:
# TEST_START
# TEST_TYPE = config_bisect
# CONFIG_BISECT_TYPE = build
# CONFIG_BISECT = /home/test/¢onfig-bad
# MIN_CONFIG = /home/test/config-min
+# BISECT_MANUAL = 1
