DMA: PL330: Add dma api driver

2010-05-24T03:28:19+00:00

Add DMA Engine API driver for the PL330 DMAC. This driver is supposed to be reusable by various platforms that have one or more PL330 DMACs. Atm, DMA_SLAVE and DMA_MEMCPY capabilities have been implemented.

DMAENGINE: Support for ST-Ericssons DMA40 block v3

2010-04-14T21:49:20+00:00

This is a straightforward driver for the ST-Ericsson DMA40 DMA controller found in U8500, implemented akin to the existing COH 901 318 driver.

dma: Add timb-dma

2010-03-26T00:18:43+00:00

Adds the support for the DMA engine withing the timberdale FPGA. The DMA channels are strict device to host, or host to device and can not be used for generic memcpy. Signed-off-by: Richard Röjfors Signed-off-by: Dan Williams

dma: Add MPC512x DMA driver

2010-03-02T05:16:42+00:00

Adds initial version of MPC512x DMA driver. Only memory to memory transfers are currenly supported. Signed-off-by: Piotr Ziecik Signed-off-by: Wolfgang Denk Signed-off-by: Anatolij Gustschin Cc: John Rigby Acked-by: Grant Likely Signed-off-by: Dan Williams

Debugging options for the DMA engine subsystem

2010-03-02T05:13:20+00:00

This adds Kconfig options for DEBUG and VERBOSE_DEBUG to the DMA engine subsystem, I got tired of editing the Makefile manually each time I want to debug things in here, modelled this on the debug switches for other subsystems and works like a charm when working on our DMA engines.

Add COH 901 318 DMA block driver v5

2009-11-20T06:45:19+00:00

This patch adds support for the ST-Ericsson COH 901 318 DMA block, found in the U300 series platforms. It registers a DMA slave for device I/O and also a memcpy slave for memcpy. Signed-off-by: Linus Walleij Acked-by: Maciej Sosnowski Signed-off-by: Dan Williams

async_tx: build-time toggling of async_{syndrome,xor}_val dma support

2009-11-20T06:21:03+00:00

ioat3.2 does not support asynchronous error notifications which makes the driver experience latencies when non-zero pq validate results are expected. Provide a mechanism for turning off async_xor_val and async_syndrome_val via Kconfig. This approach is generally useful for any driver that specifies ASYNC_TX_DISABLE_CHANNEL_SWITCH and would like to force the async_tx api to fall back to the synchronous path for certain operations.
