|
|
|
Required properties:
|
|
- compatible: should be one of the followings.
|
|
- "mediatek,mt2701-audio"
|
|
- "mediatek,mt7622-audio"
|
|
- interrupts: should contain AFE and ASYS interrupts
|
|
- interrupt-names: should be "afe" and "asys"
|
|
- power-domains: should define the power domain
|
|
- clocks: Must contain an entry for each entry in clock-names
|
|
See ../clocks/clock-bindings.txt for details
