Merge tag 'spi-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/misc
Pull spi updates from Mark Brown: "No framework work here, only a bunch of driver updates of varying sizes: - Factoring out of the core hardware support from the MXS MMC driver by Marek Vasut to allow the hardware to also be used for SPI. - Lots of error handling cleanups from Guenter Roeck - Removal of the existing Tegra driver which is quite comprehensively broken as detailed in the changelog for the removal. - DT suppport for the PL022 and GPIO drivers. - pinctrl support for OMAP and PL022."
