  Merge remote-tracking branch 'regmap/topic/bulk' into regmap-next (2012-03-14 13:15:48 +0000)

----------------------------------------------------------------

Things are really quieting down with the regmap API, while we're still
seeing a trickle of new features coming in they're getting much smaller
than they were.  It's also nice to have some features which support
other subsystems building infrastructure on top of regmap.  Highlights
include:

- Support for padding between the register and the value when
  interacting with the device, sometimes needed for fast interfaces.
- Support for applying register updates to the device when restoring the
  register state.  This is intended to be used to apply updates supplied by
  manufacturers for tuning the performance of the device (many of which
  are to undocumented registers which aren't otherwise covered).
- Support for multi-register operations on cached registers.
- Support for syncing only part of the register cache.
- Stubs and parameter query functions intended to make it easier for other
  subsystems to build infrastructure on top of the regmap API.

plus a few driver updates making use of the new features which it was
easier to merge via this tree.
