We still need to rework the whole irqchip stuff for sun6i/sun8i, which have 1 parent interrupt per EINT capable pin bank. Earlier discussions with Maxime (on IRC IIRC) suggested moving this over to gpiolib irqchip helpers might be more work than using our own irqchip implementation, requiring 1 gpiochip per pin group?
