sudmac: add support for SUDMAC

2013-04-30T10:20:12Z

Some Renesas USB modules have SUDMAC. This patch supports it using the shdma-base driver. Signed-off-by: Yoshihiro Shimoda Reviewed-by: Guennadi Liakhovetski Acked-by: Kuninori Morimoto Signed-off-by: Vinod Koul

dma: sh: add Kconfig

2013-04-30T10:20:12Z

This patch adds Kconfig in the drivers/dma/sh. This patch also adds a new config "SH_DMAE_BASE" and the "config SH_DMAE" depends on it. Since some drivers (e.g. sh_mmcif.c) depends on shdma-base.c if CONFIG_DMA_ENGINE=y, the "config SH_DMAE_BASE" is set as "bool".

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

2013-02-26T17:24:48Z

Pull slave-dmaengine updates from Vinod Koul: "This is fairly big pull by my standards as I had missed last merge window. So we have the support for device tree for slave-dmaengine, large updates to dw_dmac driver from Andy for reusing on different architectures. Along with this we have fixes on bunch of the drivers" Fix up trivial conflicts, usually due to #include line movement next to each other. * 'next' of git://git.infradead.org/users/vkoul/slave-dma: (111 commits) Revert "ARM: SPEAr13xx: Pass DW DMAC platform data from DT" ARM: dts: pl330: Add #dma-cells for generic dma binding support DMA: PL330: Register the DMA controller with the generic DMA helpers DMA: PL330: Add xlate function DMA: PL330: Add new pl330 filter for DT case. dma: tegra20-apb-dma: remove unnecessary assignment edma: do not waste memory for dma_mask dma: coh901318: set residue only if dma is in progress dma: coh901318: avoid unbalanced locking dmaengine.h: remove redundant else keyword dma: of-dma: protect list write operation by spin_lock dmaengine: ste_dma40: do not remove descriptors for cyclic transfers dma: of-dma.c: fix memory leakage dw_dmac: apply default dma_mask if needed dmaengine: ioat - fix spare sparse complain dmaengine: move drivers/of/dma.c -> drivers/dma/of-dma.c ioatdma: fix race between updating ioat->head and IOAT_COMPLETION_PENDING dw_dmac: add support for Lynxpoint DMA controllers dw_dmac: return proper residue value dw_dmac: fill individual length of descriptor ...

dma: sh/shdma-base.c: remove unnecessary null pointer check

2013-01-20T13:49:40Z

the variable chan is dereferenced in line 635, so it is no reason to check null again in line 641. Signed-off-by: Cong Ding Signed-off-by: Vinod Koul

dma: sh: Don't use ENODEV for failing slave lookup

2013-01-08T06:05:06Z

If dmaengine driver's .device_alloc_chan_resources() method returns -ENODEV, dma_request_channel() will decide, that the driver has been removed and will remove the device from its list. To prevent this use ENXIO if a slave lookup fails. Reported-by: Kuninori Morimoto Signed-off-by: Guennadi Liakhovetski Cc: stable@vger.kernel.org Signed-off-by: Vinod Koul

Drivers: dma: remove __dev* attributes.

2013-01-03T23:57:15Z

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

dmaengine: shdma: restore partial transfer calculation

2012-08-01T04:48:52Z

The recent shdma driver split has mistakenly removed support for partial DMA transfer size calculation on forced termination. This patch restores it. Signed-off-by: Guennadi Liakhovetski Acked-by: Vinod Koul Signed-off-by: Paul Mundt

dma: sh: provide a migration path for slave drivers to stop using .private

2012-07-20T05:58:20Z

This patch extends the sh dmaengine driver to support the preferred channel selection and configuration method, instead of using the "private" field from struct dma_chan. We add a standard filter function to be used by slave drivers instead of implementing their own ones, and add support for the DMA_SLAVE_CONFIG control operation, which must accompany the new channel selection method. We still support the legacy .private channel allocation method to cater for a smooth driver migration. Signed-off-by: Guennadi Liakhovetski [applied a trvial checkpath fix] Signed-off-by: Vinod Koul
