-* Amlogic Audio SPDIF Input
-
-Required properties:
-- compatible: 'amlogic,axg-spdifin' or
-	      'amlogic,g12a-spdifin' or
-	      'amlogic,sm1-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.
-
-Optional property:
-- resets: phandle to the dedicated reset line of the spdif input.
-
-Example on the A113 SoC:
-
-spdifin: audio-controller at 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";
-};
