Yep :) ain't it nice.

The only problem I see now is that these APIs seem to expect the use of
global GPIO numbers?

No they don't, only if you use the deprecated pinctrl_add_gpio_range().

Instead, when you register your struct gpio_chip, use
gpiochip_add_pin_range() and this will use relative offsets
without relying on global GPIO numbers.

This latter call replaces pinctrl_add_gpio_range().

I hope I'm not missing something here?

You're missing gpiochip_add_pin_range() ;)
