| 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 |
