[PATCH] drm/mediatek: Add MT8188 Overlay Driver Data

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

 



Add MT8188 overlay driver configuration data. This change consequently
enables 10-bit overlay support on MT8188 devices.

Tested by running ChromeOS UI on MT8188 and using modetest -P. AR30 and
BA30 overlays are confirmed to work from modetest.
