When the + phone approaches the human body, it will actively reduce the transmit + power of the antenna to keep the SAR within a safe range. Therefore, + we also refer to the proximity sensor as a SAR sensor. + +properties: + compatible: + enum: + - awinic,aw96103 + - awinic,aw96105 + + reg: + maxItems: 1 + + interrupts: + description: + Generated by the device to announce that a close/far + proximity event has happened. + maxItems: 1 + + vcc-supply: + description: + Optional regulator for chip, 1.7V-3.6V. + +required: + - compatible + - reg + - interrupts + - vcc-supply + +additionalProperties: false + +examples: + - | + #include <dt-bindings/interrupt-controller/irq.h> + i2c { + #address-cells = <1>; + #size-cells = <0>; + proximity@12 { + compatible = "awinic,aw96103"; + reg = <0x12>; + interrupt-parent = <&gpio>; + interrupts = <23 IRQ_TYPE_EDGE_FALLING>; + vcc-supply = <&pp1800_prox>; + }; + }; -- 2.45.1
