- * FIXME: Should we set up the GPIO domain here?
- *
- * The problem is that we cannot put the interrupt resources into the platform
- * device until the irqdomain has been added. Right now, we set the GIC interrupt
- * domain from init_irq(), then load the gpio driver from
- * core_initcall(nmk_gpio_init) and add the platform devices from
- * arch_initcall(customize_machine).
- *
- * This feels fragile because it depends on the gpio device getting probed
- * _before_ any device uses the gpio interrupts.
