When the 19*b2d2a78aSEmmanuel Vadot phone approaches the human body, it will actively reduce the transmit 20*b2d2a78aSEmmanuel Vadot power of the antenna to keep the SAR within a safe range. Therefore, 21*b2d2a78aSEmmanuel Vadot we also refer to the proximity sensor as a SAR sensor. 22*b2d2a78aSEmmanuel Vadot 23*b2d2a78aSEmmanuel Vadotproperties: 24*b2d2a78aSEmmanuel Vadot compatible: 25*b2d2a78aSEmmanuel Vadot enum: 26*b2d2a78aSEmmanuel Vadot - awinic,aw96103 27*b2d2a78aSEmmanuel Vadot - awinic,aw96105 28*b2d2a78aSEmmanuel Vadot 29*b2d2a78aSEmmanuel Vadot reg: 30*b2d2a78aSEmmanuel Vadot maxItems: 1 31*b2d2a78aSEmmanuel Vadot 32*b2d2a78aSEmmanuel Vadot interrupts: 33*b2d2a78aSEmmanuel Vadot description: 34*b2d2a78aSEmmanuel Vadot Generated by the device to announce that a close/far 35*b2d2a78aSEmmanuel Vadot proximity event has happened. 36*b2d2a78aSEmmanuel Vadot maxItems: 1 37*b2d2a78aSEmmanuel Vadot 38*b2d2a78aSEmmanuel Vadot vcc-supply: true 39*b2d2a78aSEmmanuel Vadot 40*b2d2a78aSEmmanuel Vadotrequired: 41*b2d2a78aSEmmanuel Vadot - compatible 42*b2d2a78aSEmmanuel Vadot - reg 43*b2d2a78aSEmmanuel Vadot - interrupts 44*b2d2a78aSEmmanuel Vadot - vcc-supply 45*b2d2a78aSEmmanuel Vadot 46*b2d2a78aSEmmanuel VadotadditionalProperties: false 47*b2d2a78aSEmmanuel Vadot 48*b2d2a78aSEmmanuel Vadotexamples: 49*b2d2a78aSEmmanuel Vadot - | 50*b2d2a78aSEmmanuel Vadot #include <dt-bindings/interrupt-controller/irq.h> 51*b2d2a78aSEmmanuel Vadot i2c { 52*b2d2a78aSEmmanuel Vadot #address-cells = <1>; 53*b2d2a78aSEmmanuel Vadot #size-cells = <0>; 54*b2d2a78aSEmmanuel Vadot proximity@12 { 55*b2d2a78aSEmmanuel Vadot compatible = "awinic,aw96103"; 56*b2d2a78aSEmmanuel Vadot reg = <0x12>; 57*b2d2a78aSEmmanuel Vadot interrupt-parent = <&gpio>; 58*b2d2a78aSEmmanuel Vadot interrupts = <23 IRQ_TYPE_EDGE_FALLING>; 59*b2d2a78aSEmmanuel Vadot vcc-supply = <&pp1800_prox>; 60*b2d2a78aSEmmanuel Vadot }; 61*b2d2a78aSEmmanuel Vadot }; 62
