[Freedreno] [PATCH v4 5/7] drm/msm/a6xx: Ensure CX collapse during gpu recovery

2022-08-17 Thread Akhil P Oommen
Because there could be transient votes from other drivers/tz/hyp which may keep the cx gdsc enabled, we should poll until cx gdsc collapses. We can use the reset framework to poll for cx gdsc collapse from gpucc clk driver. This feature requires support from the platform's gpucc driver. Signed-of
