| 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>; | |
| }; | |
| }; |
