MAX9860 Mono Audio Voice Codec
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : "maxim,max9860"
|
||||
|
||||
- reg : the I2C address of the device
|
||||
|
||||
- AVDD-supply, DVDD-supply and DVDDIO-supply : power supplies for
|
||||
the device, as covered in bindings/regulator/regulator.txt
|
||||
|
||||
- clock-names : Required element: "mclk".
|
||||
|
||||
- clocks : A clock specifier for the clock connected as MCLK.
|
||||
|
||||
Examples:
|
||||
|
||||
max9860: max9860@10 {
|
||||
compatible = "maxim,max9860";
|
||||
reg = <0x10>;
|
||||
|
||||
AVDD-supply = <®_1v8>;
|
||||
DVDD-supply = <®_1v8>;
|
||||
DVDDIO-supply = <®_3v0>;
|
||||
|
||||
clock-names = "mclk";
|
||||
clocks = <&pck2>;
|
