[PATCH v3 00/14] drm: Create drm_output_color_format enum

[Maxime Ripard]

Hi,

This series creates an enum to represent the output color format as an
enum instead of a bitmask, and consolidate the HDMI helpers to use the
new enum.

This should make Nicolas' work easier.

It has been build tested, and passes kunit tests.

Let me know what you think,
Maxime
