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";
|
|
};
