    Subject[PATCH 4/5] dt-bindings: mfd: maxim,max77843: add MAX77843 bindings
    Date
    Document the bindings for MAX77843 MFD driver, based on Exynos5433 TM2
    devicetree. These are neither accurate nor finished bindings but at
    least allow parsing existing DTS files.

    The example DTS was copied from existing DTS
    (exynos5433-tm2-common.dtsi), so keep the license as GPL-2.0-only.

    +description: |
    + This is a part of device tree bindings for Maxim MAX77843 MicroUSB
    + Integrated Circuit (MUIC).
    +
    + The Maxim MAX77843 is a MicroUSB and Companion Power Management IC which
    + includes voltage current regulators, charger, fuel-gauge, haptic motor driver
    + and MicroUSB management IC.
