The gpio framework uses the irq_domain at sfp->gc.irq.domain, so
shouldn't this be set before registering the gpio_chip with
devm_gpiochip_add_data above?

It is devm_gpiochip_add_data() that create the domain, so there is
nothing to set before.

Thanks,

Ah, no. sfp->gc.irq.domain is a pointer to an irq_domain that is
initialised when adding the gpio_chip.
