1 * CSR SiRFSoC DMA controller
6 - compatible: Should be "sirf,prima2-dmac", "sirf,atlas7-dmac" or
8 - reg: Should contain DMA registers location and length.
9 - interrupts: Should contain one interrupt shared by all channel
10 - #dma-cells: must be <1>. used to represent the number of integer
11 cells in the dmas property of client device.
12 - clocks: clock required
17 dmac0: dma-controller@b00b0000 {
18 compatible = "sirf,prima2-dmac";
19 reg = <0xb00b0000 0x10000>;
27 Fill the specific dma request line in dmas. In the below example, spi0 read
28 channel request line is 9 of the 2nd dma controller, while write channel uses
29 4 of the 2nd dma controller; spi1 read channel request line is 12 of the 1st
30 dma controller, while write channel uses 13 of the 1st dma controller:
33 compatible = "sirf,prima2-spi";
36 dma-names = "rx", "tx";
40 compatible = "sirf,prima2-spi";
43 dma-names = "rx", "tx";
