|
|
Required properties:
|
|
|
|
- compatible: Should contain "ti,ts3a227e".
|
|
- reg: The i2c address. Should contain <0x3b>.
|
|
- interrupts: Interrupt number for /INT pin from the 227e
|
|
|
|
Optional properies:
|
|
- ti,micbias: Intended MICBIAS voltage (datasheet section 9.6.7).
|
|
Select 0/1/2/3/4/5/6/7 to specify MICBIAS voltage
|
|
2.1V/2.2V/2.3V/2.4V/2.5V/2.6V/2.7V/2.8V
|
|
Default value is "1" (2.2V).

|
Examples:
|
|
|
|
i2c {
|
|
ts3a227e@3b {
|
|
compatible = "ti,ts3a227e";
|
|
reg = <0x3b>;
|
|
interrupt-parent = <&gpio>;
|
|
interrupts = <3 IRQ_TYPE_LEVEL_LOW>;
