[PATCH] drm/nouveau: Add support for clockgating on Fermi+
...ou enable.
Are you 110% sure that fiddling with 0x20200 bits without first setting
these values can *never* cause any issues with stability or correctness,
even under the weirdest of loads?

[PATCH] drm/nouveau: Add support for clockgating on Fermi+
This adds support for enabling automatic clockgating on nvidia GPUs for
Fermi and later generations. This saves a little bit of power, bringing
my fermi GPU's power consumption from ~28.3W on idle to ~27W, and my
kepler's idle power consumption from ~23.6W to ~21.65W.
Similar to how the nvidia driver seems to handle this, we enable
clockgating for each engine that supports it after
