-Subject: [PATCH 0896/1110] drm/amd/dal: zero out current context on suspend
-
-Since everything shuts down on S3, the states stored in current
-context are no longer valid and should be zeroed to make sure
-they don't confuse DC level optimization into incorrectly skipping
-hw programming. For the S3 issue on Tonga, the display clock was
-always hard coded, therefore not changing on resuming, so ended
-up not being programmed due to optimization. This change fixes
-S3 resume on Tonga.
