1	ST-Ericsson COH 901 318 DMA Controller
2	
3	This is a DMA controller which has begun as a fork of the
4	ARM PL08x PrimeCell VHDL code.
5	
6	Required properties:
7	- compatible: should be "stericsson,coh901318"
8	- reg: register locations and length
9	- interrupts: the single DMA IRQ
10	- #dma-cells: must be set to <1>, as the channels on the
11	  COH 901 318 are simple and identified by a single number
12	- dma-channels: the number of DMA channels handled
13	
14	Example:
15	
16	dmac: dma-controller@c00020000 {
17		compatible = "stericsson,coh901318";
18		reg = <0xc0020000 0x1000>;
19		interrupt-parent = <&vica>;
20		interrupts = <2>;
21		#dma-cells = <1>;
22		dma-channels = <40>;
23	};
24	
25	Consumers example:
26	
27	uart0: serial@c0013000 {
28		compatible = "...";
29		(...)
30		dmas = <&dmac 17 &dmac 18>;
31		dma-names = "tx", "rx";
32	};
