[PATCH 1/2] dt-bindings: iio: adc: Introduce ADS7138

From: Tobias Sperling
Date: Wed Nov 13 2024 - 08:52:49 EST


Add documentation for the driver of ADS7128 and ADS7138 12-bit, 8-channel
analog-to-digital converters. These ADCs have a wide operating range and
a wide feature set. Communication is based on the I2C interface.
