avr32: at32ap700x: specify DMA src and dst masters
Browse files Browse the repository at this point in the history
Now that the dw_dmac DMA driver supports configurable source and
destination masters we need to specify which ones to use. This was
previously hardcoded to 0 and 1 respectively in the driver.
