[PATCH v2 1/2] dt-bindings: iio: light: veml6075: document rset-ohms

From: Javier Carrasco
Date: Thu Oct 24 2024 - 16:45:16 EST


The veml6070 provides a configurable integration time by means of an
external resistor (Rset in the datasheet) with values between 75 and
1200 kohms.

Document rset-ohms to select the integration time.
