Could the following be used as a suitable example.

#include <dt-bindings/interrupt-controller/irq.h>

i2c {
    #address-cells = <1>;
    #size-cells = <0>;

    light-sensor@53 {
        compatible = "liteon,ltr390";
        reg = <0x53>;
        interrupts = <18 IRQ_TYPE_EDGE_FALLING>;
        vdd-supply = <&vdd_regulator>;
    };
};

Thanks for the review.

Best regards,
Anshul
