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
