From 50f3b016b055dbc83094bc2d7a91c3c69edbc88b Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 27 Mar 2013 00:44:56 +0100 Subject: [PATCH] drm/i915: add pipe_config->limited_color_range Now that we have a useful struct for this, let's use it. Some neat pointer-chasing required, but it's all there already. v2: Rebased on top of the added Haswell limited color range support.
