| * 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>; |
| }; |
