  drm/nouveau/dp: fix support for dpms · 4874322e
  由 Ben Skeggs 提交于 5月 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.

This previously worked for the most part due to userspace doing a

properly handle cases where sync is lost for other reasons, or if
userspace isn't caring.

There's also provisions to allow a pad to be locked with a specific

future patches.

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

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.
