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>;

		};

	};
