Merge tag 'spi-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "A fairly quiet release for SPI, mainly driver work.  A few highlights:

   - Supports bits per word compatibility checking in the core.
   - Allow use of the IP used in Freescale SPI controllers outside
     Freescale SoCs.
   - DMA support for the Atmel SPI driver.
   - New drivers for the BCM2835 and Tegra114"
