We don't realistically have the clock cycles to do that on a low end embedded processor handling high speed I/O. The best you can do is trigger a workqueue to switch the buffer data around and call the helper while the uart may be receiving more bytes. What you are asking for you'd get out of the first parts of tidying up the receive paths because you'd set a different port->rx() method and get bursts of characters, flags and length data.
