Subject: Question: GPIO driver how to get irq_base

Hi GPIO maintainer,

Need your help.
I want to add interrupt function to gpio/pch_gpio.c

According to other upstreamed GPIO driver, (e.g. pl061, langwell, etc...)
2 IRQs(irq, irq_base) are used.

I can get "irq" from (struct pci_dev *)pdev->irq.
However I can't understand where can I get the "irq_base".
Let me know how to get.

Thanks,
