     ST-Ericsson COH 901 318 DMA Controller
     
     This is a DMA controller which has begun as a fork of the
     ARM PL08x PrimeCell VHDL code.
     
     Required properties:
     - compatible: should be "stericsson,coh901318"
     - reg: register locations and length
     - interrupts: the single DMA IRQ
    - #dma-cells: must be set to <1>, as the channels on the
      COH 901 318 are simple and identified by a single number
    - dma-channels: the number of DMA channels handled
    
    Example:
    
    dmac: dma-controller@c00020000 {
            compatible = "stericsson,coh901318";
            reg = <0xc0020000 0x1000>;
            interrupt-parent = <&vica>;
            interrupts = <2>;
            #dma-cells = <1>;
            dma-channels = <40>;
    };
    
    Consumers example:
    
    uart0: serial@c0013000 {
            compatible = "...";
            (...)
            dmas = <&dmac 17 &dmac 18>;
            dma-names = "tx", "rx";
    };
