Merge tag 'spi-v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown:
"Quite a lot of activity in SPI this cycle, almost all of it in drivers
with a few minor improvements and tweaks in the core.
- Updates to pxa2xx to support Intel Broxton and multiple chip selects.
- Support for big endian in the bcm63xx driver.
- Multiple slave support for the mt8173
- New driver for the auxiliary SPI controller in bcm2835 SoCs.
- Support for Layerscale SoCs in the Freescale DSPI driver"
