[PATCH 1/3] dt-bindings: power: supply: Add DT schema for richtek,rt5033-battery

From: Stephan Gerhold
Date: Mon May 17 2021 - 06:38:21 EST


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.
