    +* 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";
    +};
