-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>;
