Subject[PATCH v5 3/3] gpio: uniphier: add UniPhier GPIO controller driver
Date
This GPIO controller is used on UniPhier SoC family.

It also serves as an interrupt controller, but interrupt signals are
just delivered to the parent irqchip without any latching or OR'ing.
This is implemented by using hierarchy IRQ domain.
