Merge tag 'regmap-3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap

Pull regmap updates from Mark Brown:
 "Quite a few enhancements this time around, helpers and diagnostics for
  the most part which is good to see:

   - Addition of table based lookups for the register access checks from
     Davide Ciminaghi, making life easier for drivers with big blocks of
     similar registers.
   - Allow drivers to get the irqdomain for regmap irq_chips, allowing
     the domain to be used with other APIs.
   - Debug improvements for paged register maps.
   - Performance improvments for some of the diagnostic infrastructure,
     very helpful for devices with large register maps."
