dmaengine: at_hdmac: new driver for the Atmel AHB DMA Controller
This AHB DMA Controller (aka HDMA or DMAC on AT91 systems) is availlable on at91sam9rl chip. It will be used on other products in the future. This first release covers only the memory-to-memory tranfer type. This is the only tranfer type supported by this chip. On other products, it will be used also for peripheral DMA transfer (slave API support to come). I used dmatest client without problem in different configurations to test it. Full documentation for this controller can be found in the SAM9RL datasheet: http://www.atmel.com/dyn/products/product_card.asp?part_id=4243 Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Acked-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
