+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
