Merge tag 'spi-v3.19-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi fixes from Mark Brown:
 "A few driver specific fixes here, the DMA burst size increase in the
  spfi driver is a fix to make the hardware happier in some situations"

* tag 'spi-v3.19-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi:
  spi: img-spfi: Increase DMA burst size
  spi: img-spfi: Enable controller before starting TX DMA
