2021-04-14gpio: Support ROHM BD71815 GPOsMatti Vaittinen1-0/+185
Support GPO(s) found from ROHM BD71815 power management IC. The IC has two GPO pins but only one is properly documented in the 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 the data-sheet. Control for this undocumented pin can be enabled using a special DT property. This driver is derived from work by Peter Yang <yanglsh@embest-tech.com> although not so much of the original is left.
