Boards with gpu subsystem, such as 8MP, have gpu device and gpu2d, gpu3d sub-devices. gpu2d and gpu3d devices have enabled runtime pm while gpu device not. But gpu runtime pm suspend and resume callbacks are binded to gpu device, which leads to gpu runtime pm callback not working. So we enable runtime pm of gpu device in gpu subsystem to request/release high bus freq when GPU work/idle. Signed-off-by: Guangliu Ding <guangliu.ding@nxp.com> |
