   1Freescale i.MX System Reset Controller
   2======================================
   3
   4Please also refer to reset.txt in this directory for common reset
   5controller binding usage.
   6
   7Required properties:
   8- compatible: Should be "fsl,<chip>-src"
   9- reg: should be register base and length as documented in the
  10  datasheet
  11- interrupts: Should contain SRC interrupt and CPU WDOG interrupt,
  12  in this order.
  13- #reset-cells: 1, see below
  14
  15example:
  16
  17src: src@020d8000 {
  18        compatible = "fsl,imx6q-src";
  19        reg = <0x020d8000 0x4000>;
  20        interrupts = <0 91 0x04 0 96 0x04>;
  21        #reset-cells = <1>;
  22};
  23
  24Specifying reset lines connected to IP modules
  25==============================================
  26
  27The system reset controller can be used to reset the GPU, VPU,
  28IPU, and OpenVG IP modules on i.MX5 and i.MX6 ICs. Those device
  29nodes should specify the reset line on the SRC in their resets
  30property, containing a phandle to the SRC device node and a
  31RESET_INDEX specifying which module to reset, as described in
  32reset.txt
  33
  34example:
  35
  36        ipu1: ipu@02400000 {
  37                resets = <&src 2>;
  38        };
  39        ipu2: ipu@02800000 {
  40                resets = <&src 4>;
  41        };
  42
  43The following RESET_INDEX values are valid for i.MX5:
  44GPU_RESET     0
  45VPU_RESET     1
  46IPU1_RESET    2
  47OPEN_VG_RESET 3
  48The following additional RESET_INDEX value is valid for i.MX6:
  49IPU2_RESET    4
