- * Freescale MPC512x and MPC8308 DMA Controller
- The DMA controller in Freescale MPC512x and MPC8308 SoCs can move
- blocks of memory contents between memory and peripherals or
- from memory to memory.
- Refer to "Generic DMA Controller and DMA request bindings" in
- the dma/dma.txt file for a more detailed description of binding.
- Required properties:
- - compatible: should be "fsl,mpc5121-dma" or "fsl,mpc8308-dma";
- - reg: should contain the DMA controller registers location and length;
- - interrupt for the DMA controller: syntax of interrupt client node
- is described in interrupt-controller/interrupts.txt file.
- - #dma-cells: the length of the DMA specifier, must be <1>.
- Each channel of this DMA controller has a peripheral request line,
- the assignment is fixed in hardware. This one cell
- in dmas property of a client device represents the channel number.
- Example:
- dma0: dma@14000 {
- compatible = "fsl,mpc5121-dma";
- reg = <0x14000 0x1800>;
- interrupts = <65 0x8>;
- #dma-cells = <1>;
- };
- DMA clients must use the format described in dma/dma.txt file.
