Required properties:
4
-
- compatible: 'amlogic,axg-tdm-iface'
5
-
- clocks: list of clock phandle, one for each entry clock-names.
6
-
- clock-names: should contain the following:
7
-
* "sclk" : bit clock.
8
-
* "lrclk": sample clock
9
-
* "mclk" : master clock
10
-
-> optional if the interface is in clock slave mode.
11
-
- #sound-dai-cells: must be 0.

Example of TDM_A on the A113 SoC:

tdmif_a: audio-controller@0 {
