[RFC PATCH 0/7] Simplify and correct msm/dp bridge implementation

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

 



I noticed that commit 8a3b4c17f863 ("drm/msm/dp: employ bridge mechanism for display
enable and disable") conflicts with the panel-edp (panel bridge)
support. Both bridges will try to attach directly to the drm encoder
itself. I started writing lengthy letter describing what is broken and
how it should be fixed. Then at some point I stopped and quickly coded
this RFC (which is compile-tested only).

Comments and tests (on both DP and eDP setups) are more than welcome.

The following changes since commit 6ed95285382d6f90a3c3a11d5806a5eb7db715c3:

  drm/msm/a5xx: Fix missing CP_PROTECT for SMMU on A540 (2021-12-17 15:09:46 -0800)
