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

While reading the HDMI 2.0 spec I noticed some new things related to
the RGB quantization range stuff, and after cross checking with
CEA-861-F I spotted a some other things as well. So I figured I should
pimp up the code a bit.

And since we now have two drivers that deal with this stuff, I decided
to move a bunch of the code to the core to avoid duplicating the code
and having different bugs/features for each driver. I still left the state
computation part in the drivers, but eventually we might want to move that
code into some helper as well.

Entire series available here:

Ville Syrjälä (5):
  drm/edid: Have drm_edid.h include hdmi.h
  drm/edid: Introduce drm_default_rgb_quant_range()
  drm/edid: Introduce drm_hdmi_avi_infoframe_quant_range()
  drm/edid: Set AVI infoframe Q even when QS=0
  drm/edid: Set YQ bits in the AVI infoframe according to CEA-861-F
