[PATCH 4.14 13/31] drm/edid: Add 6 bpc quirk for BOE panel in HP Pavilion 15-n233sl

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

 



4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Kai-Heng Feng <kai.heng.feng@xxxxxxxxxxxxx>

commit 0711a43b6d84ff9189adfbf83c8bbf56eef794bf upstream.

There's another panel that reports "DFP 1.x compliant TMDS" but it
supports 6bpc instead of 8 bpc.

Apply 6 bpc quirk for the panel to fix it.
