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.
