[PATCH 5.6 127/177] drm/amd/display: Added locking for atomic update stream and update planes

From: Greg Kroah-Hartman
Date: Mon Jun 01 2020 - 14:36:58 EST


From: Anthony Koo <Anthony.Koo@xxxxxxx>

[ Upstream commit 009114f6df84150a567b05537aa29b9d660e419b ]

[Why]
Screen flickering when HDR switches between FP16 and ARGB2101010

[How]
Moved pipe_control_lock so stream update and plane update occur atomically
