Subject: [PATCH 1/3] dt-bindings: power: supply: Add DT schema for richtek,rt5033-battery
Date: Mon, 17 May 2021 12:35:52 +0200 [thread overview]
Message-ID: <20210517103554.168159-2-stephan@gerhold.net> (raw)
In-Reply-To: <20210517103554.168159-1-stephan@gerhold.net>
The RT5033 PMIC provides a simple fuel gauge via I2C.
Add a DT schema to describe how to set it up in the device tree.
Note that although RT5033 is a MFD with lots of functionality
(also charger, regulator, LEDs, ...) the fuel gauge has a separate
I2C bus and is not part of the MFD.
