- 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>.
- - interrupt-parent: The parent interrupt controller
- - 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 MACBIAS 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>;
- };
- };
