From 64804a6d513cba428ed0e9b5cac8967e4c24a180 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Mon, 8 Sep 2014 13:38:02 +1000 Subject: [PATCH] drm/gk104-/fb/ram: use parsed timing data in mr routines All the other chipsets should be moved over to this too. It's not needed yet for the upcoming commits, so left this step as it'll conflict badly with Roy's GT21x reclocking work.
