So there is this corner case where some GPIO driver does some pinctrl business, I mean, really really little of it. And then it may be overkill. Sometimes though, the hardware actually can do a lot of this biasing and muxing it just wasn't part of the driver yet or done in e.g. boot loaders, and then it's usually better to use pinctrl. Adding custom APIs to the GPIO drivers will however always cause a maintenance burden on the GPIO maintainers, so that's why pinctrl & GPIO is nice. I don't know which case this would be though.
