[PATCH 5/5] drm/i915: Replace "Broadcast RGB" with "RGB quantization range" property
Yussuf Khalil
dev at pp3345.net
Mon Apr 13 21:40:26 UTC 2020
DRM now has a globally available "RGB quantization range" connector
property. i915's "Broadcast RGB" that fulfils the same purpose is now
considered deprecated, so drop it in favor of the DRM property.
