-* Amlogic Audio TDM formatters
-
-Required properties:
-- compatible: 'amlogic,axg-tdmin' or
-	      'amlogic,axg-tdmout' or
-	      'amlogic,g12a-tdmin' or
-	      'amlogic,g12a-tdmout' or
-	      'amlogic,sm1-tdmin' or
-	      'amlogic,sm1-tdmout
-- reg: physical base address of the controller and length of memory
-       mapped region.
-- clocks: list of clock phandle, one for each entry clock-names.
-- clock-names: should contain the following:
-  * "pclk"     : peripheral clock.
-  * "sclk"     : bit clock.
-  * "sclk_sel" : bit clock input multiplexer.
-  * "lrclk"    : sample clock
-  * "lrclk_sel": sample clock input multiplexer
-
-Optional property:
-- resets: phandle to the dedicated reset line of the tdm formatter.
-
-Example of TDMOUT_A on the S905X2 SoC:
-
-tdmout_a: audio-controller@500 {
-	compatible = "amlogic,axg-tdmout";
-	reg = <0x0 0x500 0x0 0x40>;
-	resets = <&clkc_audio AUD_RESET_TDMOUT_A>;

-		 <&clkc_audio AUD_CLKID_TDMOUT_A_SCLK_SEL>,
-		 <&clkc_audio AUD_CLKID_TDMOUT_A_LRCLK>,
-		 <&clkc_audio AUD_CLKID_TDMOUT_A_LRCLK>;
-	clock-names = "pclk", "sclk", "sclk_sel",
-		      "lrclk", "lrclk_sel";
