Merge branch 'next' of git://git.infradead.org/users/vkoul/slave-dma
Pull slave-dmaengine changes from Vinod Koul: "This brings for slave dmaengine: - Change dma notification flag to DMA_COMPLETE from DMA_SUCCESS as dmaengine can only transfer and not verify validaty of dma transfers - Bunch of fixes across drivers: - cppi41 driver fixes from Daniel - 8 channel freescale dma engine support and updated bindings from Hongbo - msx-dma fixes and cleanup by Markus - DMAengine updates from Dan: - Bartlomiej and Dan finalized a rework of the dma address unmap implementation. - In the course of testing 1/ a collection of enhancements to dmatest fell out. Notably basic performance statistics, and fixed / enhanced test control through new module parameters 'run', 'wait', 'noverify', and 'verbose'. Thanks to Andriy and Linus [Walleij] for their review. - Testing the raid related corner cases of 1/ triggered bugs in the recently added 16-source operation support in the ioatdma driver. - Some minor fixes / cleanups to mv_xor and ioatdma" * 'next' of git://git.infradead.org/users/vkoul/slave-dma: (99 commits) dma: mv_xor: Fix mis-usage of mmio 'base' and 'high_base' registers dma: mv_xor: Remove unneeded NULL address check ioat: fix ioat3_irq_reinit ioat: kill msix_single_vector support raid6test: add new corner case for ioatdma driver ioatdma: clean up sed pool kmem_cache ioatdma: fix selection of 16 vs 8 source path ioatdma: fix sed pool selection ioatdma: Fix bug in selftest after removal of DMA_MEMSET. dmatest: verbose mode dmatest: convert to dmaengine_unmap_data dmatest: add a 'wait' parameter dmatest: add basic performance metrics dmatest: add support for skipping verification and random data setup dmatest: use pseudo random numbers dmatest: support xor-only, or pq-only channels in tests dmatest: restore ability to start test at module load and init dmatest: cleanup redundant "dmatest: " prefixes dmatest: replace stored results mechanism, with uniform messages Revert "dmatest: append verify result to results" ...
