[Intel-gfx] [v7][PATCH 00/12] drm/i915: adding state checker for gamma lut values

[Swati Sharma]

In this patch series, added state checker to validate gamma
and will be extended to validate degamma lut values aswell.
This reads hardware state, and compares the originally
requested state to the state read from hardware.

v1: -Implementation done for legacy platforms
     (removed all the placeholders) (Jani)
v2: -Restructured code and created platform specific patch series for
     gamma validation
v3: -Rebase
v4: -Minor changes-function name changes mainly
v5: -Added degamma validation (Ville)
v6: -Removed degamma changes, debugging was becoming difficult
    -Added function to assign bit_precision for gamma/degamma lut values /platform
    -Added debug info into intel_dump_pipe_config() (Jani)
v7: -Added platform specific functions to compute gamma bit precision on the
     basis of GAMMA_MODE (Ville)

Swati Sharma (12):
  drm/i915: Introduce vfunc read_luts() to create hw lut
  drm/i915: Enable intel_color_get_config()
  drm/i915: Add intel_color_lut_equal() to compare hw and sw
    gamma/degamma lut values
  drm/i915: Extract i9xx_read_luts()
  drm/i915: Extract chv_read_luts()
  drm/i915: Extract i965_read_luts()
  drm/i915: Extract icl_read_luts()
  drm/i915: Extract glk_read_luts()
  drm/i915: Extract bdw_read_luts()
  drm/i915: Extract ivb_read_luts()
  drm/i915: Extract ilk_read_luts()
  FOR_TESTING_ONLY: Print rgb values of hw and sw blobs
