Subject: [PATCH v2 1/4] dt-bindings: iio: proximity: Add RF Digital RFD77402 ToF sensor

The RF Digital RFD77402 is a Time-of-Flight (ToF) proximity and distance
sensor that provides absolute and highly accurate distance measurements
from 100 mm up to 2000 mm over an I²C interface. It includes an optional
interrupt pin that signals when new measurement data is ready.
