Not much improved. See other NXP bindings how they do this.

That's odd to always require two reserved ranges. Does this mean all
devices have exactly the same reserved GPIOs? Then the driver should not
export them.

This is a friendly reminder during the review process.

It seems my or other reviewer's previous comments were not fully
addressed. Maybe the feedback got lost between the quotes, maybe you
just forgot to apply it. Please go back to the previous discussion and
either implement all requested changes or keep discussing them.

Thank you.


Best regards,
