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

- 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
