Dear Maintainers,
I am planning to submit a patch to add support for one of our PCIe to
UART(16550) modules.I have found the the following tree in the
MAINTAINERS file for 8250/16?50 serial drivers.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git

The master branch in this tree doesn't have any check in from 2020-06-
14.

What check specifically are you looking for?  What commit id?

I would like to know which branch to be used as a base to generate
and submit the patch. 

If this is a bugfix, you can make it against the tty-linus or main
branch, as the main branch tracks Linus's current tree within a -rc or
two, and the tty-linus branch has the fixes that I will be sending to
him for this release.

If it is for a new feature, the tty-next branch is what you should make
it against.

If you have any problems with this, please let me know.

thanks,

greg k-h
