-SiRF internal audio CODEC
-
-Required properties:
-
- - compatible : "sirf,atlas6-audio-codec" or "sirf,prima2-audio-codec"
-
- - reg : the register address of the device.
-
- - clocks: the clock of SiRF internal audio codec
-
-Example:
-
-audiocodec: audiocodec@b0040000 {
- compatible = "sirf,atlas6-audio-codec";
- reg = <0xb0040000 0x10000>;
- clocks = <&clks 27>;

-* 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>;
-};
