[PATCH 0/3] drm/msm/dp: Fix and utilize TPG with a debugfs

[Abhinav Kumar]

DP Test Patten Generator is a very useful tool to debug issues such
as blank screen or corruption seen on the DP monitor by isolating it
to whether the corruption is coming from further upstream such as DPU
OR from the DP controller and below. It was noted in [1] that this API
is unused. Rather than dropping the API, it should be fixed and used.

Hence, this series fixes the DP Test Patten Generator API and also utilizes
it by adding a debugfs for it.
