Subject: [v5][PATCH 01/11] drm/i915: Introduce vfunc read_luts() to create hw lut
Date: Sat,  4 May 2019 22:41:30 +0530	[thread overview]
Message-ID: <1556989900-21972-2-git-send-email-swati2.sharma@intel.com> (raw)
In-Reply-To: <1556989900-21972-1-git-send-email-swati2.sharma@intel.com>

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
