* Amlogic Audio SPDIF Output
Required properties:
- compatible: 'amlogic,axg-spdifout'
- clocks: list of clock phandle, one for each entry clock-names.
- clock-names: should contain the following:
* "pclk" : peripheral clock.
* "mclk" : master clock
- #sound-dai-cells: must be 0.
Example on the A113 SoC:
spdifout: audio-controller@480 {
compatible = "amlogic,axg-spdifout";
reg = <0x0 0x480 0x0 0x50>;
#sound-dai-cells = <0>;
clocks = <&clkc_audio AUD_CLKID_SPDIFOUT>,
<&clkc_audio AUD_CLKID_SPDIFOUT_CLK>;
clock-names = "pclk", "mclk";
};
