Texas Instruments TS3A227E
Autonomous Audio Accessory Detection and Configuration Switch
The TS3A227E detect headsets of 3-ring and 4-ring standards and
switches automatically to route the microphone correctly. It also
handles key press detection in accordance with the Android audio
headset specification v1.0.
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>;
};
};
