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

Pull spi updates from Mark Brown:
 "For this release SPI has been exceptionally quiet, all the work has
  been on improving drivers (including taking advantage of some of the
  recent framework updates):

   - DMA support for the rspi driver providing a nice performance boost
   - performance improvement for the SIRF controller in PIO mode
   - new support for the Cadence SPI IP and for pxa2xx on BayTrail"
