+* Amlogic Audio SPDIF Input
+
+Required properties:
+- compatible: 'amlogic,axg-spdifin'
+- interrupts: interrupt specifier for the spdif input.
+- clocks: list of clock phandle, one for each entry clock-names.
+- clock-names: should contain the following:
+ * "pclk" : peripheral clock.
+ * "refclk" : spdif input reference clock
+- #sound-dai-cells: must be 0.
+
+Example on the A113 SoC:
+
+spdifin: audio-controller@400 {
+ compatible = "amlogic,axg-spdifin";
+ reg = <0x0 0x400 0x0 0x30>;
+ #sound-dai-cells = <0>;
+ interrupts = <GIC_SPI 87 IRQ_TYPE_EDGE_RISING>;
+ clocks = <&clkc_audio AUD_CLKID_SPDIFIN>,
+ <&clkc_audio AUD_CLKID_SPDIFIN_CLK>;
+ clock-names = "pclk", "refclk";
+};
