MAX98090 audio CODEC
2
-
3
-
This device supports I2C only.
4
-
5
-
Required 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
-
13
-
Optional 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
22
-
23
-
- maxim,micbias: Micbias voltage applies to the analog mic, valid voltages value are:
