In linux device driver, is it possible to register an ISR for multiple
irq lines?

Yes, use request_irq with the same handler for each of your irq lines.
You couldn't easily do this at once in a single request_xxx instruction,
because registration may succeed on some lines, but fail on some others
ones. The registration status would then be more difficult to manage.

Is there any possibility 2 assign explicitly an IRQ or change the IRQ for a
specific device after it has been assigned an IRQ.
TIA
