[Nouveau] [PATCH 0/4] Some initial tidy-ups and refactoring
The patches contain some tidy-up work, and refactoring that has arisen
as a by-product of my initial work on adding TV support to nv50.
Joel Holdsworth (4):
drm/nouveau: Removed unneeded include in nvc0_fence.c
drm/nouveau: Replaced magic numbers with defines from nouveau_reg
drm/nouveau: Replaced copy-pasted nv_wait with nv50_wait_dpms_ctrl
helper
drm/nouveau: Refactored encoder create functions into common
nv50_encoder_create helper

[Nouveau] [PATCH 2/4] drm/nouveau: Replaced magic numbers with defines from nouveau_reg
As you've no doubt noticed, using "magic" numbers is the convention used throughout the driver (except dispnv04 which is in a world of its own), rather than the (occasional) macros. It's a trade-off, since the magic numbers are a little harder to read, but they're much easier to match up in traces. Eventually you start to remember what the various numbers mean... or you can look them up with the "lookup" utility in envytools.
