From 6af31a653d6c8e1708c27b7f32cafd5435b3bb90 Mon Sep 17 00:00:00 2001 From: Damien Lespiau Date: Fri, 28 Mar 2014 00:18:33 +0530 Subject: [PATCH] drm/i915/skl: Introduce intel_num_planes() It can be handy to get the number of planes for this pipe, ie including the primary plane to loop over them. Introduce a little function to do so.
