* 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";
};
