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" ...

dmaengine: remove DMA unmap from drivers

2013-11-14T19:04:38Z

Remove support for DMA unmapping from drivers as it is no longer needed (DMA core code is now handling it).

dmaengine: prepare for generic 'unmap' data

2013-11-14T00:25:06Z

Add a hook for a common dma unmap implementation to enable removal of the per driver custom unmap code. (A reworked version of Bartlomiej Zolnierkiewicz's patches to remove the custom callbacks and the size increase of dma_async_tx_descriptor for drivers that don't care about raid).

DMA: Freescale: update driver to support 8-channel DMA engine

2013-11-13T08:56:27Z

This patch adds support to 8-channel DMA engine, thus the driver works for both the new 8-channel and the legacy 4-channel DMA engines. Signed-off-by: Hongbo Zhang Signed-off-by: Vinod Koul

drivers: clean-up prom.h implicit includes

2013-10-10T01:04:04Z

Powerpc is a mess of implicit includes by prom.h. Add the necessary explicit includes to drivers in preparation of prom.h cleanup. Signed-off-by: Rob Herring Acked-by: Grant Likely

fsldma: remove useless use of lock

2013-08-05T04:02:24Z

Accordingly to dma_cookie_status() description locking is not required. Signed-off-by: Andy Shevchenko Cc: Li Yang Cc: Zhang Wei Cc: linuxppc-dev@lists.ozlabs.org Signed-off-by: Vinod Koul

dma: use platform_{get,set}_drvdata()

2013-07-05T06:10:32Z

Use the wrapper functions for getting and setting the driver data using platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev, so we can directly pass a struct platform_device. Also, unnecessary dev_set_drvdata() is removed, because the driver core clears the driver data to NULL after device_release or on probe failure. Signed-off-by: Jingoo Han Signed-off-by: Vinod Koul

dma: remove use of __devinit

2012-11-28T20:42:36Z

CONFIG_HOTPLUG is going away as an option so __devinit is no longer needed. Signed-off-by: Bill Pemberton Cc: Li Yang Cc: Zhang Wei Cc: Barry Song Acked-by: Viresh Kumar Signed-off-by: Greg Kroah-Hartman
