* sh: Move sh4a dma header from cpu-sh4 to cpu-sh4a.Paul Mundt2012-05-191-85/+0
| | | | | | | cpu-sh4a headers take priority over cpu-sh4 ones by virtue of the build system, there's no need to try and mingle sh4a stuff in cpu-sh4. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: cpu dma evt2irq migration.Paul Mundt2012-05-181-44/+46
| | | | | | | This migrates the cpu-family relative DMA IRQ definitions over to evt2irq() backed hwirq lookups. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* dmaengine: shdma: separate DMA headers.Guennadi Liakhovetski2010-03-021-62/+0
| | | | | | | | | | Separate SH DMA headers into ones, commonly used by both drivers, and ones, specific to each of them. This will make the future development of the dmaengine driver easier.

* sh: implement DMA_SLAVE capability in SH dmaengine driverGuennadi Liakhovetski2010-02-081-7/+8
| | | | | | | | Tested to work with a SIU ASoC driver on sh7722 (migor). Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Acked-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: fix Transfer Size calculation in both DMA driversGuennadi Liakhovetski2010-02-081-24/+73
| | | | | | | | | | | | | Both the original arch/sh/drivers/dma/dma-sh.c and the new SH dmaengine drivers do not take into account bits 3:2 of the Transfer Size field in the CHCR register, besides, bit-field defines set bit 2, but the mask only passes bits 1:0 through. TS_16BLK and TS_32BLK macros are bogus too. This patch fixes all these issues for sh7722 and sh7724, other CPUs stay unchanged and might need to be fixed too.

* sh: dmaengine support for sh7724.Guennadi Liakhovetski2009-12-171-4/+4
| | | | | | | | Add a dmaengine platform device to sh7724, fix DMA channel interrupt numbers. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Add SH7724 DMAC support.Kuninori Morimoto2009-08-041-1/+2

* sh: dma-sh updates for multi IRQ and new SH-4A CPUs.Nobuhiro Iwamatsu2009-03-101-0/+94
This adds DMA support for newer SH-4A CPUs, particularly SH7763/64/80/85. This also enables multi IRQ support for platforms that have multiple vectors bound to the same IRQ source.
