+Freescale i.MX System Reset Controller
+======================================
+
+Please also refer to reset.txt in this directory for common reset
+controller binding usage.
+
+Required properties:
+- compatible: Should be "fsl,<chip>-src"
+- reg: should be register base and length as documented in the
+ datasheet
+- interrupts: Should contain SRC interrupt and CPU WDOG interrupt,
+ in this order.
+- #reset-cells: 1, see below
+
+example:
+
+src: src@020d8000 {
+ compatible = "fsl,imx6q-src";
+ reg = <0x020d8000 0x4000>;
+ interrupts = <0 91 0x04 0 96 0x04>;
+ #reset-cells = <1>;
+};
+
+Specifying reset lines connected to IP modules
+==============================================
+
+The system reset controller can be used to reset the GPU, VPU,
+IPU, and OpenVG IP modules on i.MX5 and i.MX6 ICs. Those device
+nodes should specify the reset line on the SRC in their resets
+property, containing a phandle to the SRC device node and a
+RESET_INDEX specifying which module to reset, as described in
+reset.txt
+
+example:
+
+ ipu1: ipu@02400000 {
+ resets = <&src 2>;
+ };
+ ipu2: ipu@02800000 {
+ resets = <&src 4>;
+ };
+
+The following RESET_INDEX values are valid for i.MX5:
+GPU_RESET 0
+VPU_RESET 1
+IPU1_RESET 2
+OPEN_VG_RESET 3
+The following additional RESET_INDEX value is valid for i.MX6:
+IPU2_RESET 4
- interrupts: Should contain sync interrupt and error interrupt,
in this order.
- #crtc-cells: 1, See below
+- resets: phandle pointing to the system reset controller and
+ reset line index, see reset/fsl,imx-src.txt for details
example:
compatible = "fsl,imx53-ipu";
reg = <0x18000000 0x080000000>;
interrupts = <11 10>;
+ resets = <&src 2>;

+ * This file is licensed under the terms of the GNU General Public
+ * License version 2. This program is licensed "as is" without any
+ * warranty of any kind, whether express or implied.
+ *
+ * The Marvell EBU SoCs have a configurable physical address space:
+ * the physical address at which certain devices (PCIe, NOR, NAND,
+ * etc.) sit can be configured. The configuration takes place through
+ * two sets of registers:
+ *
+ * - One to configure the access of the CPU to the devices. Depending
+ * on the families, there are between 8 and 20 configurable windows,
+ * each can be use to create a physical memory window that maps to a
+ * specific device. Devices are identified by a tuple (target,
+ * attribute).
+ *
+ * - One to configure the access to the CPU to the SDRAM. There are
+ * either 2 (for Dove) or 4 (for other families) windows to map the
+ * SDRAM into the physical address space.
+ *
+ * This driver:
+ *
+ * - Reads out the SDRAM address decoding windows at initialization
+ * time, and fills the mvebu_mbus_dram_info structure with these
+ * informations. The exported function mv_mbus_dram_info() allow
+ * device drivers to get those informations related to the SDRAM
+ * address decoding windows. This is because devices also have their
+ * own windows (configured through registers that are part of each
+ * device register space), and therefore the drivers for Marvell
+ * devices have to configure those device -> SDRAM windows to ensure
+ * that DMA works properly.
+ *
+ * - Provides an API for platform code or device drivers to
+ * dynamically add or remove address decoding windows for the CPU ->
+ * device accesses. This API is mvebu_mbus_add_window(),
+ * mvebu_mbus_add_window_remap_flags() and
+ * mvebu_mbus_del_window(). Since the (target, attribute) values
+ * differ from one SoC family to another, the API uses a 'const char
+ * *' string to identify devices, and this driver is responsible for
+ * knowing the mapping between the name of a device and its
+ * corresponding (target, attribute) in the current SoC family.
+ *
+ * - Provides a debugfs interface in /sys/kernel/debug/mvebu-mbus/ to
+ * see the list of CPU -> SDRAM windows and their configuration
+ * (file 'sdram') and the list of CPU -> devices windows and their
+ * configuration (file 'devices').
