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."
