MAX98090 audio CODEC
|
|
This device supports I2C only.
|
|
Required properties:
|
|
- compatible : "maxim,max98090" or "maxim,max98091".
|
|
- reg : The I2C address of the device.
|
|
- interrupts : The CODEC's interrupt output.

|
Optional properties:
|
|
- clocks: The phandle of the master clock to the CODEC
|
|
- clock-names: Should be "mclk"
|
|
- #sound-dai-cells : should be 0.
|
|
- maxim,dmic-freq: Frequency at which to clock DMIC
