Subject: [PATCH v2 5/6] drm/i915: Clean up rotation DSPCNTR/DVSCNTR/etc. setup
Date: Fri, 21 Oct 2016 22:22:47 +0300	[thread overview]
Message-ID: <1477077768-4274-6-git-send-email-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <1477077768-4274-1-git-send-email-ville.syrjala@linux.intel.com>

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

Move the plane control register rotation setup away from the
coordinate munging code. This will result in neater looking
code once we add reflection support for CHV.

v2: Drop the BIT(), drop some usless parens,
