1ST-Ericsson COH 901 318 DMA Controller
2
3This is a DMA controller which has begun as a fork of the
4ARM PL08x PrimeCell VHDL code.
5
6Required 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
14Example:
15
16dmac: 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
25Consumers example:
26
27uart0: serial@c0013000 {
28 compatible = "...";
29 (...)
30 dmas = <&dmac 17 &dmac 18>;
31 dma-names = "tx", "rx";
32};
