| * 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. |
