AFAICT the current gpio-ranges do match the number of GPIOs (ngpios) in
the pinctrl drivers for all/most of the platforms you update below. It
looks like the special UFS_RESET pins are also exported as GPIOs in
addition to the real GPIOs. I'm not sure if this is intended or a
mistake.
In any case, the gpio-ranges should match the "ngpios" in the driver,
otherwise the driver exposes more GPIOs than advertised by the DT.
So I think the same change should be made in the driver as well if the
UFS pins are not supposed to be exposed as GPIOs.
Thanks,
Stephan
