0001 * Freescale MPC512x and MPC8308 DMA Controller
0002
0003 The DMA controller in Freescale MPC512x and MPC8308 SoCs can move
0004 blocks of memory contents between memory and peripherals or
0005 from memory to memory.
0006
0007 Refer to "Generic DMA Controller and DMA request bindings" in
0008 the dma/dma.txt file for a more detailed description of binding.
0009
0010 Required properties:
0011 - compatible: should be "fsl,mpc5121-dma" or "fsl,mpc8308-dma";
0012 - reg: should contain the DMA controller registers location and length;
0013 - interrupt for the DMA controller: syntax of interrupt client node
0014 is described in interrupt-controller/interrupts.txt file.
0015 - #dma-cells: the length of the DMA specifier, must be <1>.
0016 Each channel of this DMA controller has a peripheral request line,
0017 the assignment is fixed in hardware. This one cell
0018 in dmas property of a client device represents the channel number.
0019
0020 Example:
0021
0022 dma0: dma@14000 {
0023 compatible = "fsl,mpc5121-dma";
0024 reg = <0x14000 0x1800>;
0025 interrupts = <65 0x8>;
0026 #dma-cells = <1>;
0027 };
0028
0029 DMA clients must use the format described in dma/dma.txt file.
