Thank you for your patch. There is something to discuss/improve.

If you have 210 GPIOs, then this should be 210.

This says you have 210 GPIOs.

Keep these four enum values sorted alphabetically.

This is not allowed. Please rebase on pinctrl maintainer tree or next.

Wrong number of pins. You have 210, right? This should be number of
GPIOs + optionally UFS reset.
