UPSTREAM: drm/edid: Set YQ bits in the AVI infoframe according to CEA-861-F
CEA-861-F tells us:
"When transmitting any RGB colorimetry, the Source should set the
YQ-field to match the RGB Quantization Range being transmitted
(e.g., when Limited Range RGB, set YQ=0 or when Full Range RGB,
set YQ=1) and the Sink shall ignore the YQ-field."
So let's go ahead and do that. Perhaps there are sinks that don't
ignore the YQ as they should for RGB?
I wasn't able to find similar text in CEA-861-E, so it would seem
to be a fairly "recent" addition.
