The raw_spinlock in the IMX GPCV2 interupt chip is not initialized before usage. That results in a lockdep splat: INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator. Add the missing raw_spin_lock_init() to the setup code.

Since we now have a generic data structure to express an interrupt specifier, convert all hierarchical irqchips that are OF based to use a fwnode_handle as part of their alloc and xlate (which becomes translate) callbacks. As most of these drivers have dependencies (they exchange IRQ specifiers), change them all in a single, massive patch...

The struct irq_domain contains a "struct device_node *" field (of_node) that is almost the only link between the irqdomain and the device tree infrastructure. In order to prepare for the removal of that field, convert all users to use irq_domain_get_of_node() instead.

IMX7D contains a new version of GPC IP block (GPCv2). It has two major functions: power management and wakeup source management. When the system is in WFI (wait for interrupt) mode, the GPC block will be the first block on the platform to be activated and signaled. In normal wait mode during cpu idle, the system can be woken up by any enabled interrupts. In standby or suspend mode, the system can only be wokem up by the pre-defined wakeup sources.
