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."
Pulling from Mark Brown as Grant Likely is still busy moving.
