[Intel-gfx] [RFC v1 0/6] drm/edid: overhaul displayid iterator

[Jani Nikula]

Iterating DisplayID is overcomplicated as it is, and it's not getting
easier when we eventually add support for DisplayID from DDC 0xA4
instead of EDID extensions. Prepare by abstracting the complexities away
from EDID code.

Untested, let's see what our CI thinks. ;)


Jani Nikula (6):
  drm/edid: make a number of functions, parameters and variables const
  drm/displayid: add separate drm_displayid.c
  drm/displayid: add new displayid section/block iterators
  drm/edid: use the new displayid iterator for detailed modes
  drm/edid: use the new displayid iterator for finding CEA extension
  drm/edid: use the new displayid iterator for tile info
