   1ST-Ericsson COH 901 318 DMA Controller
   2
   3This is a DMA controller which has begun as a fork of the
   4ARM PL08x PrimeCell VHDL code.
   5
   6Required properties:
   7- compatible: should be "stericsson,coh901318"
   8- reg: register locations and length
   9- interrupts: the single DMA IRQ
  10- #dma-cells: must be set to <1>, as the channels on the
  11  COH 901 318 are simple and identified by a single number
  12- dma-channels: the number of DMA channels handled
  13
  14Example:
  15
  16dmac: dma-controller@c00020000 {
  17        compatible = "stericsson,coh901318";
  18        reg = <0xc0020000 0x1000>;
  19        interrupt-parent = <&vica>;
  20        interrupts = <2>;
  21        #dma-cells = <1>;
  22        dma-channels = <40>;
  23};
  24
  25Consumers example:
  26
  27uart0: serial@c0013000 {
  28        compatible = "...";
  29        (...)
  30        dmas = <&dmac 17 &dmac 18>;
  31        dma-names = "tx", "rx";
  32};
