Subject[PATCH 7/9] irqchip/gic-v3-its: Initialize its nodes later
Date
Use an initcall to initialize its. This allows us to use the device
framework during initialization that is up at this point. We use
subsys_initcall() here since we need the arch to be initialized
first. It is before pci and platform device probe where devices are
bound to msi interrupts.
