   1 ST-Ericsson COH 901 318 DMA Controller
   2
   3 This is a DMA controller which has begun as a fork of the
   4 ARM PL08x PrimeCell VHDL code.
   5
   6 Required 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
  14 Example:
  15
  16 dmac: 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
  25 Consumers example:
  26
  27 uart0: serial@c0013000 {
  28         compatible = "...";
  29         (...)
  30         dmas = <&dmac 17 &dmac 18>;
  31         dma-names = "tx", "rx";
  32 };
