+title: Freescale i.MX System Reset Controller
+

+
+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
