+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>;
+ };
+ };
