The IC has two GPO pins but only one is properly documented in data-sheet. The driver exposes by default only the documented GPO. The second GPO is connected to E5 pin and is marked as GND in data-sheet. Control for this undocumented pin can be enabled using a special DT property. This driver is derived from work by Peter Yang although not so much of original is left.
