- drm/nouveau/dp: fix support for dpms · 4874322e
  Ben Skeggs authored May 31, 2014
```
SOR_PWR has no effect to power-off DP links, unlike other SOR protocols.

Instead, on the source side, we cut power to the lanes after having put
the sink into D3.  Link training takes care of everything required to
bring it back again.

- drm/nouveau/disp/dp: maintain link in response to hpd signal · 55f083c3
  Ben Skeggs authored May 20, 2014
```
This previously worked for the most part due to userspace doing a
modeset in response to HPD interrupts.  This will allow us to
properly handle cases where sync is lost for other reasons, or if
userspace isn't caring.

- drm/nouveau/i2c: introduce locking at a per-port level · 9efc583e
  Ben Skeggs authored May 29, 2014
```
There's also provisions to allow a pad to be locked with a specific
routing, for an indefinite period of time.  This will be used in
future patches.

The G94+ pad driver will now also power-down pads when not required.

- drm/nouveau/i2c: balance port acquire/release · d2ae2eb4
  Ben Skeggs authored May 29, 2014
```
This was a half-finished hack before, just enough to handle the shared
aux/i2c pad thing on G94 and up.

We got lucky with locking etc up until now, as this was (generally) all
protected by the DRM mode_config lock.  It's about to become a lot more
likely to hit the races.
