In linux kernel since version 5.1 (release Date: 2019-05-05)  
Support for GPIOs on ROHM BD71828 PMIC. There are three GPIOs
available on the ROHM PMIC in total. The GPIOs are limited to
outputs only and pins must be configured to GPIO outputs by
OTP. Enable this only if you want to use these pins as outputs.

This driver can also be built as a module. If so, the module
will be called gpio-bd71828.
