Merge remote-tracking branches 'spi/topic/s3c64xx', 'spi/topic/ti-qspi' and 'spi/topic/txx9' into spi-next (2015-11-04 11:02:16 +0000)

----------------------------------------------------------------
spi: Updates for v4.4

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.

----------------------------------------------------------------

There's quite a few trivial conflicts with "spi: Drop owner assignments
from spi_drivers". I was in two minds about including that here or just
pushing separate cleanup patches to individual drivers/subsystems, I can
respin with the patch dropped if you prefer.
