From: Ben Skeggs Date: Fri, 4 Nov 2016 07:20:36 +0000 (+1000) Subject: drm/nouveau/kms/nv50: separate out lut commit X-Git-Tag: v4.14-rc1~1925^2~38^2~24 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a7ae1561909d27e6104cbc85655f31a962ec8683;p=platform%2Fkernel%2Flinux-rpi.git drm/nouveau/kms/nv50: separate out lut 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.
