Hi Bartosz,

Thank you for the patch. These new pinctrl_gpio_*_new() functions now seem to
have the same signature as the starfive_gpio_*() functions. Is there a reason
they can't be used as callbacks directly so we could just delete the
starfive_gpio_*() wrapppers?

Also it'd be great to be to be CC'd on at least the first generic patches where
the new functions are introduced to have some context without having to look it
up on lore.
