[PATCH 2/4] dt-bindings: power: supply: maxim,max77693: convert to dtschema

From: Krzysztof Kozlowski <hidden>
Date: 2021-12-28 16:39:51
Also in: linux-leds, linux-pm, lkml
Subsystem: maxim muic charger drivers for exynos based boards, maxim pmic and muic drivers for exynos based boards, open firmware and flattened device tree bindings, power supply class/subsystem and drivers, the rest · Maintainers: Krzysztof Kozlowski, Chanwoo Choi, Rob Herring, Conor Dooley, Sebastian Reichel, Linus Torvalds

Convert the Charger bindings of Maxim MAX77693 MUIC to DT schema format.
The existing bindings were defined in ../bindings/mfd/max77693.txt.
