From 1f0c9eaf31bba3e1cac5534ba17602c115b76cf8 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Fri, 19 May 2017 23:59:35 +1000 Subject: [PATCH] drm/nouveau/disp/nv50-: implement a common supervisor 2.1 This makes use of all the additional routing and state added in previous commits, making it possible to deal with GM20x macro link routing, while also sharing code between the NV50 and GF119 implementations.
