1* Freescale MPC512x and MPC8308 DMA Controller 2 3The DMA controller in Freescale MPC512x and MPC8308 SoCs can move 4blocks of memory contents between memory and peripherals or 5from memory to memory. 6 7Refer to "Generic DMA Controller and DMA request bindings" in 8the dma/dma.txt file for a more detailed description of binding. 9 10Required 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. 19 20Example: 21 22 dma0: dma@14000 { 23 compatible = "fsl,mpc5121-dma"; 24 reg = <0x14000 0x1800>; 25 interrupts = <65 0x8>; 26 #dma-cells = <1>; 27 }; 28 29DMA clients must use the format described in dma/dma.txt file.
