2013-07-05dmaengine: at_hdmac: add FIFO configuration parameter to DMA DT bindingLudovic Desroches1-2/+5
For most devices the FIFO configuration is the same i.e. when half FIFO size is available/filled, a source/destination request is serviced. But USART devices have to do it when there is enough space/data available to perform a single AHB access so the ASAP configuration.

2013-04-30at_hdmac: move to generic DMA bindingLudovic Desroches1-5/+30
Update at_hdmac driver to support generic DMA device tree binding. Devices can still request channel with dma_request_channel() then it doesn't break DMA for non DT boards.
