From 0f2a2a756e862e1936ef599451015ca4c12efde8 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 6 Jul 2015 15:10:00 +0300 Subject: [PATCH] drm/i915: Clean up DP/HDMI limited color range handling MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
