[PATCH v4 1/7] drm/msm/disp/dpu1: clear dpu_assign_crtc and get crtc from drm_enc instead of dpu_enc

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Update crtc retrieval from dpu_enc to drm_enc, since new links get set
as part of the update legacy mode set. The dpu_enc->crtc cache is no
more needed, hence cleaning it as part of this change.
