1* SiRF SoC USP module
2
3Required properties:
4- compatible: "sirf,prima2-usp-pcm"
5- reg: Base address and size entries:
6- dmas: List of DMA controller phandle and DMA request line ordered pairs.
7- dma-names: Identifier string for each DMA request line in the dmas property.
8  These strings correspond 1:1 with the ordered pairs in dmas.
9
10  One of the DMA channels will be responsible for transmission (should be
11  named "tx") and one for reception (should be named "rx").
12
13- clocks: USP controller clock source
14- pinctrl-names: Must contain a "default" entry.
15- pinctrl-NNN: One property must exist for each entry in pinctrl-names.

18usp0: usp@b0080000 {
19	compatible = "sirf,prima2-usp-pcm";
20	reg = <0xb0080000 0x10000>;
21	clocks = <&clks 28>;
22	dmas = <&dmac1 1>, <&dmac1 2>;
23	dma-names = "rx", "tx";
24	pinctrl-names = "default";
25	pinctrl-0 = <&usp0_only_utfs_pins_a>;
