[PATCH 0/3] tty: TX helpers

[Jiri Slaby <jslaby@suse.cz>]

First, this series depends on "tty: various cleanups"
(20220411104506.8990-1-jslaby@suse.cz).

This series introduces uart_port_tx{,_limit}() TX helpers. See PATCH
1/3 for the details. Comments welcome.

Then it switches drivers to use them. First, uart_port_tx() in 2/3 and
then uart_port_tx_limit() in 3/3.

The diffstat of patches 2+3 is as follows:
 27 files changed, 330 insertions(+), 883 deletions(-)
which appears to be nice.
