From: Chen-Yu Tsai <wens@xxxxxxxx> The DMA controllers found on the H616 and H618 are the same as the one found on the A100. The only difference is the DMA endpoint (DRQ) layout. Since the number of channels and endpoints are described with additional generic properties, just add a new H616-specific compatible string and fallback to the A100 one.
