Merge tag 'spi-v3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown:
"A quiet release, more bug fixes than anything else. A few things do
stand out though:
- updates to several drivers to move towards the standard GPIO chip
select handling in the core.
- DMA support for the SH MSIOF driver.
- support for Rockchip SPI controllers (their first mainline
submission)"
