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 ] * 'for-linus' of git://git.infradead.org/users/vkoul/slave-dma: (36 commits) dmaengine: mmp_pdma: fix mismerge dma: pl08x: Export pl08x_filter_id acpi-dma: align documentation with kernel-doc format dma: fix vchan_cookie_complete() debug print DMA: dmatest: extend the "device" module parameter to 32 characters drivers/dma: fix error return code dma: omap: Set debug level to debugging messages dmaengine: fix kernel-doc style typos for few comments dma: tegra: add support for Tegra148/124 dma: dw: use %pad instead of casting dma_addr_t dma: dw: join split up messages dma: dw: fix style of multiline comment dmaengine: k3dma: fix sparse warnings dma: pl330: Use dma_get_slave_channel() in the of xlate callback dma: pl330: Differentiate between submitted and issued descriptors dmaengine: sirf: Add device_slave_caps interface DMA: Freescale: change BWC from 256 bytes to 1024 bytes dmaengine: Add MOXA ART DMA engine driver dmaengine: Add DMA_PRIVATE to BCM2835 driver dma: imx-sdma: Assign a default script number for ROM firmware cases ...
