1 * CSR SiRFSoC DMA controller
6 - compatible: Should be "sirf,prima2-dmac" or "sirf,marco-dmac"
7 - reg: Should contain DMA registers location and length.
8 - interrupts: Should contain one interrupt shared by all channel
9 - #dma-cells: must be <1>. used to represent the number of integer
10 cells in the dmas property of client device.
11 - clocks: clock required
16 dmac0: dma-controller@b00b0000 {
17 compatible = "sirf,prima2-dmac";
18 reg = <0xb00b0000 0x10000>;
26 Fill the specific dma request line in dmas. In the below example, spi0 read
27 channel request line is 9 of the 2nd dma controller, while write channel uses
28 4 of the 2nd dma controller; spi1 read channel request line is 12 of the 1st
29 dma controller, while write channel uses 13 of the 1st dma controller:
32 compatible = "sirf,prima2-spi";
35 dma-names = "rx", "tx";
39 compatible = "sirf,prima2-spi";
42 dma-names = "rx", "tx";
