SubjectRe: [PATCH] drm/bridge: parade-ps8640: Fix additional suspend/resume at bootup
Quoting yangcong (2021-11-12 00:43:02)
> Through log and waveform, we can see that there will be additional
> suspend/resume when booting. This timing does not meet the ps8640 spec.
> It seems that the delay of 500ms does not satisfied drm_panel_get_modes.
> I increased it to 900ms and it seems that this problem can be solved.
> To be safe, I'd just round up to a full 1000.
