From 7145f60a347d5676f2ac6982ed9d57dbef17a7e8 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 23 Mar 2017 21:27:07 +0200 Subject: [PATCH] drm/i915: Extract i9xx_plane_ctl() and ironlake_plane_ctl() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Pull the code to calculate the pre-SKL primary plane control register value into separate functions. Allows us to pre-compute it in the future. v2: Split the pre-ilk vs. ilk+ unification to a separate patch (Chris) Cc: Chris Wilson Signed-off-by: Ville Syrjälä Link: http://patchwork.freedesktop.org/patch/msgid/20170323192712.30682-2-ville.syrjala@linux.intel.com Reviewed-by: Chris Wilson --- drivers/gpu/drm/i915/intel_display.c | 104 +++++++++++++++++---------- 1 file changed, 66 insertions(+), 38 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 9a28a8917dc1..aa2c85b2bf78 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -2962,28 +2962,23 @@ int skl_check_plane_surface(struct intel_plane_state *plane_state) return 0;
