+* 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";
+};
