* 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>;
|
};
