Hello,
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.
