WM8962 audio CODEC
|
|
|
|
This device supports I2C only.
|
|
|
|
Required properties:
|
|
|
|
- compatible : "wlf,wm8962"
|
|
|
|
- reg : the I2C address of the device.
|
|
|
|
Optional properties:
|
|
- spk-mono: This is a boolean property. If present, the SPK_MONO bit
|
|
of R51 (Class D Control 2) gets set, indicating that the speaker is
|
|
in mono mode.
|
|
|
|
- mic-cfg : Default register value for R48 (Additional Control 4).
|
|
If absent, the default should be the register default.
|
|
|
|
- gpio-cfg : A list of GPIO configuration register values. The list must
|
|
be 6 entries long. If absent, no configuration of these registers is
|
|
performed. And note that only the value within [0x0, 0xffff] is valid.
|
|
Any other value is regarded as setting the GPIO register by its reset
|
|
value 0x0.
|
|
|
|
Example:
|
|
|
|
wm8962: codec@1a {
|
|
compatible = "wlf,wm8962";
|
|
reg = <0x1a>;
|
