[PATCH] drm/edid: Add 6 bpc quirk for edp panel enabling.

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

 



BOE panel (ID: 0x0770) that reports "DFP 1.x compliant TMDS".
But it's 6bpc panel only instead of 8 bpc.

Add panel ID to edid quirk list and set 6 bpc as default to
work around this issue.
