All-round reclocking improvements
In bulletpoints:
- Add some support for G94 and G96 reclocking. Has been tested on literally
two cards, which is hardly adequate as "full coverage". On the other hand,
the changes were small enough to make me confident this might work for others
as well.
- Fix NV50 wait for VBLANK when no monitor is plugged in.
- Voltage related inprovements for GT21x.
- Slightly improve Keplers

[PATCH v2 0/9] drm: Third attempt at fixing the fb-helper .best_encoder() mess
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Changes from the previous version mainly involve Danoie's suggestion
of hiding the drm_encoder_find() in the iterator macro. I also polished
the msm and tilcdc cases a bit more with another small helper.
