1* ZTE ZX296702 DMA controller
2
3Required properties:
4- compatible: Should be "zte,zx296702-dma"
5- reg: Should contain DMA registers location and length.
6- interrupts: Should contain one interrupt shared by all channel
7- #dma-cells: see dma.txt, should be 1, para number
8- dma-channels: physical channels supported
9- dma-requests: virtual channels supported, each virtual channel
10		have specific request line
11- clocks: clock required

13Example:
14
15Controller:
16	dma: dma-controller@09c00000{
17		compatible = "zte,zx296702-dma";
18		reg = <0x09c00000 0x1000>;
19		clocks = <&topclk ZX296702_DMA_ACLK>;
20		interrupts = <GIC_SPI 66 IRQ_TYPE_LEVEL_HIGH>;
21		#dma-cells = <1>;
22		dma-channels = <24>;
23		dma-requests = <24>;
24	};
25
26Client:
27Use specific request line passing from dmax
28For example, spdif0 tx channel request line is 4
29	spdif0: spdif0@b004000 {
30		#sound-dai-cells = <0>;
31		compatible = "zte,zx296702-spdif";
32		reg = <0x0b004000 0x1000>;
33		clocks = <&lsp0clk ZX296702_SPDIF0_DIV>;
34		clock-names = "tx";
35		interrupts = <GIC_SPI 21 IRQ_TYPE_LEVEL_HIGH>;
36		dmas = <&dma 4>;
37		dma-names = "tx";
38	}
