- 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
