* Freescale MPC512x and MPC8308 DMA Controller12The DMA controller in Freescale MPC512x and MPC8308 SoCs can move3blocks of memory contents between memory and peripherals or4from memory to memory.56Refer to "Generic DMA Controller and DMA request bindings" in7the dma/dma.txt file for a more detailed description of binding.89Required properties:10- compatible: should be "fsl,mpc5121-dma" or "fsl,mpc8308-dma";11- reg: should contain the DMA controller registers location and length;12- interrupt for the DMA controller: syntax of interrupt client node13is described in interrupt-controller/interrupts.txt file.14- #dma-cells: the length of the DMA specifier, must be <1>.15Each channel of this DMA controller has a peripheral request line,16the assignment is fixed in hardware. This one cell17in dmas property of a client device represents the channel number.1819Example:2021dma0: dma@14000 {22compatible = "fsl,mpc5121-dma";23reg = <0x14000 0x1800>;24interrupts = <65 0x8>;25#dma-cells = <1>;26};2728DMA clients must use the format described in dma/dma.txt file.293031
