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


Examples:

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