Merge branch 'for-linus' of git://git.infradead.org/users/vkoul/slave-dma
Pull slave-dma updates from Vinod Koul:
- new driver for BCM2835 used in R-pi
- new driver for MOXA ART
- dma_get_any_slave_channel API for DT based systems
- minor fixes and updates spread acrooss driver
[ The fsl-ssi dual fifo mode support addition clashed badly with the
other changes to fsl-ssi that came in through the sound merge. I did
a very rough cut at fixing up the conflict, but Nicolin Chen (author
of both sides) will need to verify and check things ]
