From: Thomas Antoine <t.antoine@xxxxxxxxxxxx>
The Maxim MAX77759 is an IC used to manage the power supply of the battery
and the USB-C. Based on drivers from google, it contains at least a PMIC,
a fuel gauge, a TCPCI and a charger.
Use max77759-fg compatible to avoid conflict with drivers for other
functions.
The Maxim MAX77759 has no non-volatile memory so it doesn't require an
address and instead requires a value for the current sensing resistor.
Keep shunt-resistor-micro-ohms optional for the MAX17201/MAX17205 as it is
not be used at the moment but could be in the future. (e.g. as a default
value to be used in case of nvmem failure)
