+* 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";
+};
