Subject: [PATCH 0/3] serial: Add uart_xmit_advance() + fixes part (of a larger patch series)

Add uart_xmit_advance() helper to handle circular xmit buffer
advancement + accounting of Tx'ed bytes. Use it to fix a few drivers
that previously lacked to accounting for DMA Tx.

Greg,
I've a another series on top this which is tty-next material making the
rest of the drivers to use uart_xmit_advance(). That series obviously
depends on the patch 1/3 of this series so if you end up putting these
3 patches into tty-linus, I'll need it to be merged into tty-next at
some point (I'm not in a big hurry with this so if you choose to delay
the merge, it's not a big deal).

Ilpo Järvinen (3):
  serial: Create uart_xmit_advance()
  serial: tegra: Use uart_xmit_advance(), fixes icount.tx accounting
  serial: tegra-tcu: Use uart_xmit_advance(), fixes icount.tx accounting
