+ MT6370 is a highly-integrated smart power management IC, which includes a
+ single cell Li-Ion/Li-Polymer switching battery charger, a USB Type-C &
+ Power Delivery (PD) controller, dual flash LED current sources, a RGB LED
+ driver, a backlight WLED driver, a display bias driver and a general LDO for
