Subject: [PATCH 02/14] drm/i915: Use skl_plane_ctl() for the SKL "sprite" planes
Date: Fri, 17 Mar 2017 23:17:56 +0200	[thread overview]
Message-ID: <20170317211808.14693-3-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20170317211808.14693-1-ville.syrjala@linux.intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

On SKL the planes are uniform so the "sprites" can use the
primary plane code perfectly fine. The only difference we
have is the color key handling, but since we never enable that
for the primary plane the same code works just fine.
