Subject: [v2][PATCH 1/3] drm/i915/display: Add gamma precision function for CHV
Date: Mon,  9 Sep 2019 17:31:41 +0530	[thread overview]
Message-ID: <1568030503-26747-2-git-send-email-swati2.sharma@intel.com> (raw)
In-Reply-To: <1568030503-26747-1-git-send-email-swati2.sharma@intel.com>

intel_color_get_gamma_bit_precision() is extended for
cherryview by adding chv_gamma_precision(), i965 will use existing
i9xx_gamma_precision() func only.
