Merge tag 'regmap-v3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap into next

Pull regmap updates from Mark Brown:
 "Another fairly quiet release, a few bug fixes and a couple of new
  features:

   - support for I2C devices connected to SMBus rather than full I2C
     controllers contributed by Boris Brezillon.  If the controller is
     only capable of SMBus operation the framework will transparently
     fall back to that

   - suport for little endian values, contributed by Xiubo Li"
