2011-07-07	ARM i.MX dma: Fix burstsize settings	Sascha Hauer	1	-1/+2
	dmaengine expects the maxburst parameter in words, not bytes. The imxdma driver and its users do this wrong. Fix this. As a side note the imx-pcm-dma-mx2 driver was 'fixed' to work with imx-dma. This broke the driver with imx-sdma support which correctly takes the maxburst parameter in words. This patch puts the sdma based sound back to work.

2011-01-31	dmaengine i.MX dma: initialize dma capabilities outside channel loop	Sascha Hauer	1	-3/+3
	The capabilities are device specific fields, not channel specific fields. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

2010-10-22	dma: imx-dma: fix signedness bug	Sascha Hauer	1	-1/+3
	mxdmac->channel was unsigned, so check (imxdmac->channel < 0) for failed imx_dma_request_by_prio() made no sence. Explicitly check signed values. Also, fix uninitialzed use of ret.

2010-10-07	dmaengine: Add Freescale i.MX1/21/27 DMA driver	Sascha Hauer	1	-0/+422
	This driver is currently implemented as a user to the old i.MX DMA API. This allows us to convert each user of the old API to the dmaengine API one by one. Once this is done the old DMA driver can be merged into the i.MX dmaengine driver.
