The MAX77693 is a companion power management IC for smart phones and tablets.
The MAX77693 contains input over-voltage protection (OVP),
a fully-integrated 2.5A switching charger for Lithium Ion battery with
integrated battery disconnect, OTG/accessory 5V output power,
a high-current white LED driver for camera flash, two safeout LDOs,
a haptic motor driver, Model Gauge m3 battery fuel gauge and MicroUSB
Interface Controller (MUIC). I2C serial interface is used for
communicating.
Add MAX77693 node to the Trats2 board. This allows using:
- charger regulator,
- 2 safeout LDO regulators (for USB OTG),
- extcon.
