VCNL4040 proximity and ambient light sensor. See datasheet at
https://www.vishay.com/docs/84274/vcnl4040.pdf
compatible: "vishay,vcnl4040"
include: [sensor-device.yaml, i2c-device.yaml]
properties:
int-gpios:
type: phandle-array
description: |
The INT pin signals that a programmable interrupt function
for ALS and PS with upper and lower thresholds has been
triggered. The sensor generates an active-low level signal
which remains asserted until the data is read.
