Hi,
I have poll-based serial port driver,
I want to make it interrupt based, so that

You need to write a "proper" serial driver. You can find ones for various
platforms under packages/devs/serial. If one doesn't already exist for
your board you can use one there as a basis, particularly if one uses the
same serial chip, e.g. 16550.
