* SiRF SoC USP module Required properties: - compatible: "sirf,prima2-usp-pcm" - reg: Base address and size entries: - dmas: List of DMA controller phandle and DMA request line ordered pairs. - dma-names: Identifier string for each DMA request line in the dmas property. These strings correspond 1:1 with the ordered pairs in dmas. One of the DMA channels will be responsible for transmission (should be named "tx") and one for reception (should be named "rx"). - clocks: USP controller clock source - pinctrl-names: Must contain a "default" entry. - pinctrl-NNN: One property must exist for each entry in pinctrl-names. Example: usp0: usp@b0080000 { compatible = "sirf,prima2-usp-pcm"; reg = <0xb0080000 0x10000>; clocks = <&clks 28>; dmas = <&dmac1 1>, <&dmac1 2>; dma-names = "rx", "tx"; pinctrl-names = "default"; pinctrl-0 = <&usp0_only_utfs_pins_a>; };
