Merge tag 'tty-5.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

2019-07-11T22:38:21+00:00

Pull tty / serial driver updates from Greg KH:
 "Here is the "large" TTY and Serial driver update for 5.3-rc1.

  It's in the negative number of lines overall as we removed an obsolete
  serial driver that was causing problems for some people who were
  trying to clean up some apis (the mpsc.c driver, which only worked for
  some pre-production hardware that no one has anymore.)

  Other than that, lots of tiny changes, cleaning up small things along
  with some platform-specific serial driver updates.

  All of these have been in linux-next for a while now with no reported
  issues"

tty: Replace ASYNC_INITIALIZED bit and update atomically

2016-04-30T16:26:55+00:00

Replace ASYNC_INITIALIZED bit in the tty_port::flags field with
TTY_PORT_INITIALIZED bit in the tty_port::iflags field. Introduce helpers
tty_port_set_initialized() and tty_port_initialized() to abstract
atomic bit ops.

Note: the transforms for test_and_set_bit() and test_and_clear_bit()
are unnecessary as the state transitions are already mutually exclusive;
the tty lock prevents concurrent open/close/hangup.

ipoctal: clear break interrupt as soon as it occurs

2014-09-24T06:26:42+00:00

In some condition we receive the break interrupt but nothing is putted
in the Rx FIFO and the correspondend bit in the status register is not
set. Thus, no-one clear the interrupt and the handler will be called
forever.

This patch clear the break interrupt as soon as it occurs. Then, if the
break character '\0' is putted in the fifo we will manage it.

We can also unmask the Break interrupt but its bit in ISR is still set
on break. So I think is better to keep the registers clean.
