The IRQ Deinitialize is used to ungate the clock. The IRQ provides the function to enable/disable interrupts. IRQ still provides functions to get and clear IRQF flags.

"WebThe approach here is to use PDC interrupt at all times (while keeping the GPIO irq disabled). The PDC interrupt handler invokes the action handler of the GPIO IRQ instead. This allows us to avoid interrupt hand-offs while entering idle states and keeps things very simple. The wake_irq_gpio_handler() is the crux of this new revision. " - Irq_type_edge_rising
