kernel.git/drivers/dma/imx-sdma.c, branch linux-3.13.y

Merge branch 'next' of git://git.infradead.org/users/vkoul/slave-dma

2013-11-20T21:20:24Z

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" ...

dma: imx-sdma: Fix warnings for LPAE builds

2013-11-13T08:40:48Z

This resolves a number of warnings such as the below when building with 64-bit dma_addr_t on arm: drivers/dma/imx-sdma.c:1092:3: warning: format '%x' expects argument of type 'unsigned int', but argument 6 has type 'dma_addr_t' [-Wformat=] ..by upcasting to u64 and using %llx.

ARM: 7857/1: dma: imx-sdma: setup dma mask

2013-10-31T14:49:19Z

The dma mask is not configured in the current code. This was triggered by soc-dmaengine-pcm which allocate the dma buffers with the imx-sdma as device. This commit fix audio on imx31. Signed-off-by: Philippe Rétornaz Acked-by: Sascha Hauer Acked-by: Vinod Koul Signed-off-by: Russell King

dma: imx-sdma: Add ROM script addresses to driver

2013-08-26T15:17:16Z

This adds the ROM script addresses for i.MX25, i.MX5x and i.MX6 to the SDMA driver needed for the driver to work without additional firmware. The ROM script addresses are SoC specific and in some cases even tapeout specific. This patch adds the ROM script addresses only for SoCs which do not have a tapeout specific SDMA ROM, because currently it's unclear how this case should be handled.

dma: imx-sdma: Use struct for driver data

2013-08-26T15:17:16Z

Use a struct type instead of an enum type for distinguishing between different versions. This makes it simpler to handle multiple differences without cluttering the code with comparisons for certain devtypes. Signed-off-by: Sascha Hauer Acked-by: Shawn Guo Signed-off-by: Vinod Koul

dma: imx-sdma: remove the unused completion

After the patch: "2ccaef0 dma: imx-sdma: make channel0 operations atomic", the "done" completion is not used any more. Just remove it. Signed-off-by: Huang Shijie Acked-by: Shawn Guo Signed-off-by: Vinod Koul

dma: use dev_get_platdata()
