1MAX98090 audio CODEC
2
3This device supports I2C only.
4
5Required properties:
6
7- compatible : "maxim,max98090" or "maxim,max98091".
8
9- reg : The I2C address of the device.
10
11- interrupts : The CODEC's interrupt output.
12
13Optional properties:
14
15- clocks: The phandle of the master clock to the CODEC
16
17- clock-names: Should be "mclk"
18
19- #sound-dai-cells : should be 0.
20
21- maxim,dmic-freq: Frequency at which to clock DMIC
