   1 * Freescale MPC512x and MPC8308 DMA Controller
   2
   3 The DMA controller in Freescale MPC512x and MPC8308 SoCs can move
   4 blocks of memory contents between memory and peripherals or
   5 from memory to memory.
   6
   7 Refer to "Generic DMA Controller and DMA request bindings" in
   8 the dma/dma.txt file for a more detailed description of binding.
   9
  10 Required properties:
  11 - compatible: should be "fsl,mpc5121-dma" or "fsl,mpc8308-dma";
  12 - reg: should contain the DMA controller registers location and length;
  13 - interrupt for the DMA controller: syntax of interrupt client node
  14         is described in interrupt-controller/interrupts.txt file.
  15 - #dma-cells: the length of the DMA specifier, must be <1>.
  16         Each channel of this DMA controller has a peripheral request line,
  17         the assignment is fixed in hardware. This one cell
  18         in dmas property of a client device represents the channel number.

  20 Example:
  21
  22         dma0: dma@14000 {
  23                 compatible = "fsl,mpc5121-dma";
  24                 reg = <0x14000 0x1800>;
  25                 interrupts = <65 0x8>;
  26                 #dma-cells = <1>;
  27         };
  28
  29 DMA clients must use the format described in dma/dma.txt file.
