Linus Walleij 607a0dcddb gpio: cadence: Pass irqchip when adding gpiochip 
We need to convert all old gpio irqchips to pass the irqchip
setup along when adding the gpio_chip. For more info see
drivers/gpio/TODO.

For chained irqchips this is a pretty straight-forward
conversion.

Jan Kotas 72ab2f7631 gpio: Add Cadence GPIO driver 
This patch adds a driver for Cadence GPIO controller.

It can be enabled with GPIO_CADENCE Kconfig option.
It uses generic GPIO infrastructure and works
as an interrupt controller.
At the moment it only supports level sensitive irqs.
