+* 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";
+};
