From 02a841d434513c7b3620250271c372fabce56de5 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Wed, 4 Jul 2012 23:44:54 +1000 Subject: drm/nouveau: restructure source tree, split core from drm implementation Future work will be headed in the way of separating the policy supplied by the nouveau drm module from the mechanisms provided by the driver core. There will be a couple of major classes (subdev, engine) of driver modules that have clearly defined tasks, and the further directory structure change is to reflect this. No code changes here whatsoever, aside from fixing up a couple of include file pathnames.
