[v1,0/3] Fixes for PSR

Message

while in virtual terminal with PSR enabled, there will be
no atomic commits triggered resulting in no screen update.
Update the dirtyfb flag into plane state during atomic check 
to flush the pixel data explicitly.

Avoid scheduling PSR commits from different work queues while
running in PSR mode already.

  drm/msm/dpu: set dirty_fb flag while in self refresh mode
  msm/disp/dpu: allow atomic_check in PSR usecase
  msm: skip the atomic commit of self refresh while PSR running

Applied, thanks!

[1/3] drm/msm/dpu: set dirty_fb flag while in self refresh mode
      https://gitlab.freedesktop.org/lumag/msm/-/commit/ddf5387d1fb7
[2/3] msm/disp/dpu: allow atomic_check in PSR usecase
      https://gitlab.freedesktop.org/lumag/msm/-/commit/86c56ba51aec

Note, patch 3, which solves a different issue (and which requires additional changes) was not applied.

Best regards,
