This makes the API much cleaner. - new IMG MDC driver by Andrew - new Renesas R-Car Gen2 DMA Controller driver by Laurent along with bunch of fixes on rcar drivers - odd fixes and updates spread over driver" * 'for-linus' of git://git.infradead.org/users/vkoul/slave-dma: (130 commits) dmaengine: pl330: add DMA_PAUSE feature dmaengine: pl330: improve pl330_tx_status() function dmaengine: rcar-dmac: Disable channel 0 when using IOMMU dmaengine: rcar-dmac: Work around descriptor mode IOMMU errata dmaengine: rcar-dmac: Allocate hardware descriptors with DMAC device dmaengine: rcar-dmac: Fix oops due to unintialized list in error ISR dmaengine: rcar-dmac: Fix spinlock issues in interrupt dmaenegine: edma: fix sparse warnings dmaengine: rcar-dmac: Fix uninitialized variable usage dmaengine: shdmac: extend PM methods dmaengine: shdmac: use SET_RUNTIME_PM_OPS() dmaengine: pl330: fix bug that cause start the same descs in cyclic dmaengine: at_xdmac: allow muliple dwidths when doing slave transfers dmaengine: at_xdmac: simplify channel configuration stuff dmaengine: at_xdmac: introduce save_cc field dmaengine: at_xdmac: wait for in-progress transaction to complete after pausing a channel ioat: fail self-test if wait_for_completion times out dmaengine: dw: define DW_DMA_MAX_NR_MASTERS dmaengine: dw: amend description of dma_dev field dmatest: move src_off, dst_off, len inside loop ...

2014-11-06Documentation: dmaengine: Add a documentation for the dma controller APIMaxime Ripard1-0/+366
The dmaengine is neither trivial nor properly documented at the moment, which means a lot of trial and error development, which is not that good for such a central piece of the system. Attempt at making such a documentation. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> [fixed some minor typos] Signed-off-by: Vinod Koul <vinod.koul@intel.com>
