1Allwinner A10 DMA Controller
2
3This driver follows the generic DMA bindings defined in dma.txt.
4
5Required properties:
6
7- compatible:	Must be "allwinner,sun4i-a10-dma"
8- reg:		Should contain the registers base address and length
9- interrupts:	Should contain a reference to the interrupt used by this device
10- clocks:	Should contain a reference to the parent AHB clock
11- #dma-cells :	Should be 2, first cell denoting normal or dedicated dma,
12		second cell holding the request line number.
13
14Example:
15	dma: dma-controller@1c02000 {
16		compatible = "allwinner,sun4i-a10-dma";
17		reg = <0x01c02000 0x1000>;
18		interrupts = <27>;
19		clocks = <&ahb_gates 6>;
20		#dma-cells = <2>;
21	};
22
23Clients:
24
25DMA clients connected to the Allwinner A10 DMA controller must use the
26format described in the dma.txt file, using a three-cell specifier for
27each channel: a phandle plus two integer cells.
28The three cells in order are:
29
301. A phandle pointing to the DMA controller.
312. Whether it is using normal (0) or dedicated (1) channels
323. The port ID as specified in the datasheet
33
34Example:
35	spi2: spi@1c17000 {
36		compatible = "allwinner,sun4i-a10-spi";
37		reg = <0x01c17000 0x1000>;
38		interrupts = <0 12 4>;
39		clocks = <&ahb_gates 22>, <&spi2_clk>;
40		clock-names = "ahb", "mod";
41		dmas = <&dma 1 29>, <&dma 1 28>;
42		dma-names = "rx", "tx";
43		#address-cells = <1>;
44		#size-cells = <0>;
45	};
