* Amlogic Audio TDM formatters

Required properties:
- compatible: 'amlogic,axg-tdmin' or
	      'amlogic,axg-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

Example of TDMOUT_A on the A113 SoC:

tdmout_a: audio-controller@500 {
	compatible = "amlogic,axg-tdmout";
	reg = <0x0 0x500 0x0 0x40>;
	clocks = <&clkc_audio AUD_CLKID_TDMOUT_A>,
		 <&clkc_audio AUD_CLKID_TDMOUT_A_SCLK>,
		 <&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";
};
