From fb4747d89b4866402fc2230022d59fa60e9e0cd5 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Wed, 1 Sep 2021 11:18:23 +0200 Subject: [PATCH] dt-bindings: hwmon: Add IIO HWMON binding Even though we had the iio-hwmon driver for some time and a number of boards using it already, we never had a binding for it. Let's add it based on what the driver expects and the boards are providing.
