| Subject: drm/edid: Add 6 bpc quirk for BOE panel in HP Pavilion 15-n233sl |
| |
| From: Kai-Heng Feng <kai.heng.feng@canonical.com> |
| |
| 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. |
