From: Ville Syrjälä Date: Mon, 6 Jul 2015 12:10:00 +0000 (+0300) Subject: drm/i915: Clean up DP/HDMI limited color range handling X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0f2a2a756e862e1936ef599451015ca4c12efde8;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Clean up DP/HDMI limited color range handling Currently we treat intel_{dp,hdmi}->color_range as partly user controller value (via the property) but we also change it during .compute_config() when using the "Automatic" mode. That is a bit confusing, so let's just change things so that we store the user property values in intel_dp, and only change what's stored in pipe_config during .compute_config(). There should be no functional change.
