-* Amlogic Audio TDM Interfaces
-
-Required properties:
-- compatible: 'amlogic,axg-tdm-iface'
-- clocks: list of clock phandle, one for each entry clock-names.
-- clock-names: should contain the following:
-  * "sclk" : bit clock.
-  * "lrclk": sample clock
-  * "mclk" : master clock
-	     -> optional if the interface is in clock slave mode.
-- #sound-dai-cells: must be 0.
-
-Example of TDM_A on the A113 SoC:
-
-tdmif_a: audio-controller@0 {
-	compatible = "amlogic,axg-tdm-iface";
-	#sound-dai-cells = <0>;
-	clocks = <&clkc_audio AUD_CLKID_MST_A_MCLK>,
-		 <&clkc_audio AUD_CLKID_MST_A_SCLK>,
-		 <&clkc_audio AUD_CLKID_MST_A_LRCLK>;
-	clock-names = "mclk", "sclk", "lrclk";
-};
