[Intel-gfx] EDID override for full RGB?

[Tom Horsley]

I'm trying to figure out which bits to flip in the
EDID info for my TV so that the Intel video driver
will be willing to use full RGB as soon as possible
(I get tired of thinking my eyes have gone bad
when I'm booting my system :-).

I built the latest git version of edid-decode,
and I see it printing this info:

  Extended tag: video capability data block
    YCbCr quantization: No Data (0)
    RGB quantization: No Data (0)

If I toggle that "RGB quantization" bit (if I can figure
out which byte it is in :-) will that be the magic
that induces the intel driver to use full range RGB
all the time?
