1 * ARM PrimeCell PL330 DMA Controller
3 The ARM PrimeCell PL330 DMA controller can move blocks of memory contents
4 between memory and peripherals or memory to memory.
7 - compatible: should include both "arm,pl330" and "arm,primecell".
8 - reg: physical base address of the controller and length of memory mapped
10 - interrupts: interrupt number to the cpu.
14 pdma0: pdma@12680000 {
15 compatible = "arm,pl330", "arm,primecell";
16 reg = <0x12680000 0x1000>;
20 Client drivers (device nodes requiring dma transfers from dev-to-mem or
21 mem-to-dev) should specify the DMA channel numbers using a two-value pair
24 [property name] = <[phandle of the dma controller] [dma request id]>;
26 where 'dma request id' is the dma request number which is connected
27 to the client controller. The 'property name' is recommended to be
28 of the form <name>-dma-channel.
30 Example: tx-dma-channel = <&pdma0 12>;
