[PATCH] drm/nouveau: Replace the iturbt_709 prop with the standarad COLOR_ENCODNIG prop

[PATCH] drm/nouveau: Replace the iturbt_709 prop with the standarad COLOR_ENCODNIG prop

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Replace the ad-hoc iturbt_709 property with the new standard
COLOR_ENCODING property. Compiles, but not tested.

s/standarad/standard/ in subject

I'd like the opportunity to test this out on real hardware, but I
don't have any pre-NV41 boards plugged in right now. I should be able
to attend to it within 7 days. If you don't hear back from me by then,
I'd appreciate a ping, as I do let things (hopefully occasionally)
slip through.

Tested this out on a NV34. Seems to work - at least the green SMPTE
bar looks different in the two different modes (had to hack modetest
to use the SMPTE pattern on planes).

I do wonder about the new color range property... that's more of a
connector thing than a plane thing no? Presumably over S-Video it's a
partial range, and over VGA it's full? I'd flip it to always full here
tbh. (Or just not provide it at all.)

Anyways, with the subject typo(s! noticed ENCODNIG -> ENCODING just
now) fixed, this is

No, this property is just about the range of the input data. Full range
YCbCr isn't exaclty common so you'd rarely need this. JPEG uses full
range I believe.

Pushed to drm-misc-next with Ben's ack.

17:27 <imirkin_> <imirkin_> friendly reminder about https://patchwork.freedesktop.org/patch/205620/ -- ville was 
                 wondering whether you'd take it, or if he should push via drm-misc.
17:27 <imirkin_> <skeggsb> ack, i'd say ville should take it in drm-misc for now
