From 7e91833dfb2d33d640ae80582f2701838532d680 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Fri, 4 Nov 2016 17:20:36 +1000 Subject: [PATCH] drm/nouveau/kms/nv50: separate out dither commit This commit separates the calculation of EVO state from the commit, in order to make the same code useful for atomic modesetting. The legacy interfaces have been wrapped on top of them.
