+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
