| Subject: drm/edid: Add 6 bpc quirk for BOE panel. |
| |
| [ Upstream commit 922dceff8dc1fb4dafc9af78139ba65671408103 ] |
| |
| BOE panel (ID: 0x0771) 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. |
