-* Amlogic Audio SPDIF Output
-
-Required properties:
-- compatible: 'amlogic,axg-spdifout' or
-	      'amlogic,g12a-spdifout' or
-	      'amlogic,sm1-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.
-
-Optional property:
-- resets: phandle to the dedicated reset line of the spdif output.
-
-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";
-};
