Merge tag 'dmaengine-4.9-rc1' of git://git.infradead.org/users/vkoul/slave-dma
Pull dmaengine updates from Vinod Koul: "This is bit large pile of code which bring in some nice additions: - Error reporting: we have added a new mechanism for users of dmaenegine to register a callback_result which tells them the result of the dma transaction. Right now only one user (ntb) is using it. - As we discussed on KS mailing list and pointed out NO_IRQ has no place in kernel, this also remove NO_IRQ from dmaengine subsystem (both arm and ppc users) - Support for IOMMU slave transfers and its implementation for arm. - To get better build coverage, enable COMPILE_TEST for bunch of driver, and fix the warning and sparse complaints on these. - Apart from above, usual updates spread across drivers" * tag 'dmaengine-4.9-rc1' of git://git.infradead.org/users/vkoul/slave-dma: (169 commits) async_pq_val: fix DMA memory leak dmaengine: virt-dma: move function declarations dmaengine: omap-dma: Enable burst and data pack for SG DT: dmaengine: rcar-dmac: document R8A7743/5 support dmaengine: fsldma: Unmap region obtained by of_iomap dmaengine: jz4780: fix resource leaks on error exit return dma-debug: fix ia64 build, use PHYS_PFN dmaengine: coh901318: fix integer overflow when shifting more than 32 places dmaengine: edma: avoid uninitialized variable use dma-mapping: fix m32r build warning dma-mapping: fix ia64 build, use PHYS_PFN dmaengine: ti-dma-crossbar: enable COMPILE_TEST dmaengine: omap-dma: enable COMPILE_TEST dmaengine: edma: enable COMPILE_TEST dmaengine: ti-dma-crossbar: Fix of_device_id data parameter usage dmaengine: ti-dma-crossbar: Correct type for of_find_property() third parameter dmaengine/ARM: omap-dma: Fix the DMAengine compile test on non OMAP configs dmaengine: edma: Rename set_bits and remove unused clear_bits helper dmaengine: edma: Use correct type for of_find_property() third parameter dmaengine: edma: Fix of_device_id data parameter usage (legacy vs TPCC) ...
