-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.
