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.
