ST-Ericsson COH 901 318 DMA Controller
This is a DMA controller which has begun as a fork of the
ARM PL08x PrimeCell VHDL code.
Required properties:
- compatible: should be "stericsson,coh901318"
- reg: register locations and length
- interrupts: the single DMA IRQ
- #dma-cells: must be set to <1>, as the channels on the
COH 901 318 are simple and identified by a single number
- dma-channels: the number of DMA channels handled
Example:
dmac: dma-controller@c00020000 {
compatible = "stericsson,coh901318";
reg = <0xc0020000 0x1000>;
interrupt-parent = <&vica>;
interrupts = <2>;
#dma-cells = <1>;
dma-channels = <40>;
};
Consumers example:
uart0: serial@c0013000 {
compatible = "...";
(...)
dmas = <&dmac 17 &dmac 18>;
dma-names = "tx", "rx";
};
