title: Freescale i.MX System Reset Controller

maintainers:
  - Philipp Zabel <p.zabel@pengutronix.de>

description: |
  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

  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
