Merge tag 'spi-fix-v4.2-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi 

Pull spi fixes from Mark Brown:
 "A small collection of pretty much unremarkable driver specific fixes
  here plus the addition of a new device ID to spidev which requires no
  other code changes"

* tag 'spi-fix-v4.2-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi:
  spi: imx: Fix small DMA transfers
  spi: zynq: missing break statement
  spi: SPI_ZYNQMP_GQSPI should depend on HAS_DMA
  spi: spidev: add compatible value for LTC2488
  spi: img-spfi: fix support for speeds up to 1/4th input clock
