Pull regulator updates from Mark Brown:
 "A fairly quiet release for the regulator API, the bulk of the changes
  being lots of small cleanups and API updates contributed by Axel Lin
  with just a small set of larger changes:

   - New driver for LP8755

   - DT support for S5M8767, TPS51632, TPS6507x and TPS65090

   - Support for writing a "commit changes" bit in the regmap helper
     functions."

88cff24159 Merge tag 'regmap-3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap updates from Mark Brown:
 "Several nice new features and performance improvements here,
  especially the first:

   - Support for using the cache infrastructure without the physical
     I/O, allowing devices which don't fit the physical model regmap has
     to take advantage of the cache infrastructure, contributed by
     Andrey Smirnov.

   - Several small improvements to the support for wake capable IRQs.

   - Support for asynchronous I/O, allowing us to come much closer to
     saturating fast buses like SPI.

   - Support for simple array caches, giving higher performance for use
     with MMIO devices.

   - Restoration of the use of bulk reads for handling interrupts,
     giving a performance improvement.

   - Support for 24 bit register addresses.

   - More performance improvements for debugfs."

1f3a574a4b Merge branch 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next
Nothing terribly exciting in here probably:
- reworked thermal stuff from mupuf/I, has a chance of possibly working
well enough when we get to being able to reclock..
- driver will report mmio access faults on chipsets where it's supported
- will now sleep waiting on fences on nv84+ rather than polling
- some cleanup of the internal fencing, looking towards sli/dmabuf sync
- initial support for anx9805 dp/tmds encoder
- nv50+ display fixes related to the above, and also might fix a few
other issues
- nicer error reporting (will log process names with channel errors)
- various other random fixes

0a0afd282f drm/nv50-/disp: move DP link training to core and train from supervisor
We need to be able to do link training for PIOR-connected ANX9805 from
the third supervisor handler (due to script ordering in the bios, can't
have the "user" call train because some settings are overwritten from
the modesetting bios scripts).

This moves link training for SOR-connected DP encoders to the second
supervisor interrupt, *before* we call the modesetting scripts (yes,
different ordering from PIOR is necessary).  This is useful since we
should now be able to remove some hacks to workaround races between
the supervisor and link training paths.
