OK, I wanted to make this configurable to preserve the current 
functional behavior although I always want to be wakeup from PMIC 
devices i.e. gpio or rtc or onkey etc.
If I understand your statement then the wake support should be there and 
should enable the wake even if there is no wake_base. The irq_set_wake() 
should be called for parent irq if client have called the irq_set_wake() 
with interrupts supported by this regmap-irq.
