When the 19 phone approaches the human body, it will actively reduce the transmit 20 power of the antenna to keep the SAR within a safe range. Therefore, 21 we also refer to the proximity sensor as a SAR sensor. 22 23properties: 24 compatible: 25 enum: 26 - awinic,aw96103 27 - awinic,aw96105 28 29 reg: 30 maxItems: 1 31 32 interrupts: 33 description: 34 Generated by the device to announce that a close/far 35 proximity event has happened. 36 maxItems: 1 37 38 vcc-supply: true 39 40required: 41 - compatible 42 - reg 43 - interrupts 44 - vcc-supply 45 46additionalProperties: false 47 48examples: 49 - | 50 #include <dt-bindings/interrupt-controller/irq.h> 51 i2c { 52 #address-cells = <1>; 53 #size-cells = <0>; 54 proximity@12 { 55 compatible = "awinic,aw96103"; 56 reg = <0x12>; 57 interrupt-parent = <&gpio>; 58 interrupts = <23 IRQ_TYPE_EDGE_FALLING>; 59 vcc-supply = <&pp1800_prox>; 60 }; 61 }; 62
