| 12 | description: | |
| 13 | The system reset controller can be used to reset the GPU, VPU, |
| 14 | IPU, and OpenVG IP modules on i.MX5 and i.MX6 ICs. Those device |
| 15 | nodes should specify the reset line on the SRC in their resets |
| 16 | property, containing a phandle to the SRC device node and a |
| 17 | RESET_INDEX specifying which module to reset, as described in |
| 18 | reset.txt |
| 19 | |
| 20 | The following RESET_INDEX values are valid for i.MX5: |
| 21 | GPU_RESET 0 |
| 22 | VPU_RESET 1 |
| 23 | IPU1_RESET 2 |
| 24 | OPEN_VG_RESET 3 |
| 25 | The following additional RESET_INDEX value is valid for i.MX6: |
| 26 | IPU2_RESET 4 |
