+ * 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.
