Otherwise 'fg' compatible suffix would not be justified. The 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 TPCI and a charger. Given I saw that the linked proposed patch, which adds a driver for the TCPCI, used the "maxim,max77759" compatible, I didn't want to create a possible eventual conflict.
