These are used with the tty_port flags which are tty generic so move the
flags into a more sensible place. This then makes it possible to add
helpers such as those suggested by Huang Shijie.

Yes, the idea looks good to me. I was actually thinking of the same.
But there are two issues with this patch (see below).

There are no minus lines in serial.h -- we have two copies of the flags
now? That looks insane.
The flags are a user API. You concealed them by the #include inside the
__KERNEL__ section (if I consider we do not have the flags defined twice).
And if we move the include outside of the __KERNEL__ section, we shall
update Kconfig, so that the new header is installed.

Allen, Could you post a formal patch?
I can change my patch based on it.

Huang - how about we add this patch first which moves the flags somewhere more sensible
and then your helper function (and probably a few others) would merge cleanly ?
