Subject: [PATCH v3 2/9] dt-bindings: iio: amplifiers: Add AD8366 support
From: Rodrigo Alencar <rodrigo.alencar@...log.com>
Add device tree binding documentation for amplifiers and digital
attenuators. This covers different device variants with similar
SPI control. Each device has its own gain range and step, hence
no fallback compatibles are used.
