combined gpio IRQCHIP

[Ramon Fried <ramon.fried@xxxxxxxxxxxxxxx>]

Hi.

I'm writing a driver for IRQ for a specific soc that has two gpiochip instances, duplicated set of registers for each bank.

The gpio chip also has IRQ support for each pin but the IRQ line for both the gpiochips  is OR'ed together.

I'm wondering what's the best approach for writing IRQ handling.

is there support for two irq_chips sharing the same parent_irq ?

Thanks,

Ramon
