Merge tag 'spi-v3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi Updates from Mark Brown:
 "A busy release for both cleanups and new drivers this time along with
  further factoring out of replicated code into the core:

   - Provide support in the core for DMA mapping transfers - essentially
     all drivers weren't implementing this properly, now there's no
     excuse.
   - Dual and quad mode support for spidev.
   - Fix handling of cs_change in the generic implementation.
   - Remove the S3C_DMA code from the s3c64xx driver now that all the
     platforms using it have been converted to dmaengine.
   - Lots of improvements to the Renesas SPI controllers.
   - Drivers for Allwinner A10 and A31, Qualcomm QUP and Xylinx xtfpga.
   - Removal of the bitrotted ti-ssp driver"
