[PATCH 2/3] dt-bindings: iio: proximity: Add Benewake TF-Luna

[Vidhu Sarwal via B4 Relay]

From: Vidhu Sarwal <vidhu.linux@xxxxxxxxx>

Add binding for the Benewake TF-Luna, a single point ToF
LiDAR distance sensor with a range of 0.2 m to 8 m.

The sensor talks either UART or I2C, selected by the level of pin 5 at
power-up. This binding covers the I2C interface. Pin 6 is a data ready
output and is described as an interrupt.
