Merge tag 'spi-v3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown:
"Not a huge amount going on this release, mainly new drivers (there's a
couple more waiting that didn't quite make the cut for this release
too):
- An interface for querying if the current transfer is the last in a
message, allowing controllers that need special handling for the
final transfer to use the core message parsing.
- Support for Amlogic Meson SPIFC, Imagination Technologies SFPI,
Intel Quark X1000 and Samsung Exynos 7 controllers"
