From 40f4628391755b5406c46e55262b9a0bd4d5d4a7 Mon Sep 17 00:00:00 2001 From: Damien Lespiau Date: Fri, 27 Feb 2015 11:15:21 +0000 Subject: [PATCH] drm/i915/skl: Adjust get_plane_config() to support Yb/Yf tiling v2: Rebased for addfb2 interface and consolidated a bit. (Tvrtko Ursulin) v3: Rebased for fb modifier changes. (Tvrtko Ursulin) v4: Use intel_fb_stride_alignment instead of open coding.
