Thanks for the contribution! Usually for chips this small we don't split them into separate units. Especially here where there's an io mux that lets you reassign the pins anyway. USB_D+ and USB_D- also seem to have their GPIO numbers wrong in the alternate functions, might be worth double-checking the mapping since I didn't check them all.

Thanks for your feedback :) I'll address it during the days.
