-* Amlogic Audio SPDIF Input
|
|
-
|
|
-Required properties:
|
|
-- compatible: 'amlogic,axg-spdifin' or
|
|
- 'amlogic,g12a-spdifin' or
|
|
- 'amlogic,sm1-spdifin'
|
|
-- interrupts: interrupt specifier for the spdif input.
|
|
-- clocks: list of clock phandle, one for each entry clock-names.
|
|
-- clock-names: should contain the following:
|
|
- * "pclk" : peripheral clock.
|
|
- * "refclk" : spdif input reference clock
|
|
-- #sound-dai-cells: must be 0.
|
|
-
|
|
-Optional property:
|
|
-- resets: phandle to the dedicated reset line of the spdif input.
|

-Example on the A113 SoC:
|
|
-
|
|
-spdifin: audio-controller@400 {
|
|
- compatible = "amlogic,axg-spdifin";
