drm/i915: Introduce vfunc read_luts() to create hw lut
In this patch, a vfunc read_luts() is introduced to create a hw lut i.e. lut having values read from gamma/degamma registers which will later be used to compare with sw lut to validate gamma/degamma lut values. v3: -Rebase v4: -Renamed intel_get_color_config to intel_color_get_config [Jani] -Wrapped get_color_config() [Jani] v5: -Renamed intel_color_get_config() to intel_color_read_luts() -Renamed get_color_config to read_luts v6: -Renamed intel_color_read_luts() back to intel_color_get_config() [Jani and Ville] Signed-off-by: Swati Sharma <swati2.sharma@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/1559123462-7343-2-git-send-email-swati2.sharma@intel.com
