Kernel-4.18.0-80.el8_act8945a

Device-Tree bindings for Active-semi ACT8945A MFD driver

Required properties:

• compatible: “active-semi,act8945a”.
• reg: the I2C slave address for the ACT8945A chip

The chip exposes two subdevices:

• a regulators: see ../regulator/act8945a-regulator.txt
• a charger: see ../power/act8945a-charger.txt

Example:
pmic@5b {
compatible = “active-semi,act8945a”;
reg = <0x5b>;

    active-semi,vsel-high;
