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"
- maxim,dmic-freq: Frequency at which to clock DMIC
- maxim,micbias: Micbias voltage applies to the analog mic, valid voltages value are:
0 - 2.2v
1 - 2.55v
2 - 2.4v
3 - 2.8v
Pins on the device (for linking into audio routes):
* MIC1
* MIC2
* DMICL
* DMICR
* IN1
* IN2
* IN3
* IN4
* IN5
* IN6
* IN12

Example:
audio-codec@10 {
compatible = "maxim,max98090";
reg = <0x10>;
interrupt-parent = <&gpio>;
interrupts = <TEGRA_GPIO(H, 4) GPIO_ACTIVE_HIGH>;
};
