[GIT PULL] regmap updates for v3.3

[Mark Brown]

Please pull the tree below to merge regmap updates for version 3.3.
After the rush of new features in version 3.2 this has been a fairly
quiet cycle for the regmap API, the main change being the wider usage by
drivers and some fixes and tweaks for them.  The main things from a
subsystem point of view are:

 - Addition of a generic interrupt controller driver which should work
   for a range of chips, saving them from having to open code this.
 - Removal of the indexed cache type as it's not got any real advantage
   over the rbtree cache.

This pull request also includes the MFD driver for the DA9052 PMIC as it
is one of the first users of the generic regmap IRQ code and therefore
has a build dependency on it.

The following changes since commit dc47ce90c3a822cd7c9e9339fe4d5f61dcb26b50:
