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>;
    };
};
