[DPU PATCH 3/5] drm/msm/dpu: remove static binding of hw pipe to plane

Sravanthi Kollukuduru skolluku at codeaurora.org
Wed Jun 20 12:50:18 UTC 2018


Expose all planes with superset of formats and with no
hw pipe static binding. Accordingly, remove checks from
atomic_check reflecting the decoupling.
