I'm not sure I got the usefulness of this change. We request GPIO line as optional, so if one is defined it in the DT/ACPI, then they probably want to (opportunistically) have it. The certain driver may or may not utilize this GPIO. With your change it's possible to have a DTS where GPIO line defined in a broken way and user won't ever know about it, if they are using platforms without termination support. -- With Best Regards, Andy Shevchenko
