linux-toradex.git/drivers/char/epca.c, branch v2.6.27.12

Fix the epca driver to permit epca_setup() to be invoked from the kernel cmdline

2008-07-22T20:03:28+00:00

Fix the epca driver to call epca_setup() if digiepca=xxx is included on the
command line and the epca driver is built in.

epca_setup() used to be called from init/main.c in 2.2 kernels, but somewhere
along the way that call was removed but not replaced.

epca: use tty_port

tty: Ldisc revamp

2008-07-21T00:12:34+00:00

Move the line disciplines towards a conventional ->ops arrangement.  For
the moment the actual 'tty_ldisc' struct in the tty is kept as part of
the tty struct but this can then be changed if it turns out that when it
all settles down we want to refcount ldiscs separately to the tty.

Pull the ldisc code out of /proc and put it with our ldisc code.

tty/serial: lay the foundations for the next set of reworks

2008-04-30T15:29:45+00:00

- Stop drivers calling their own flush method indirectly, it obfuscates code
  and it will change soon anyway

- A few more lock_kernel paths temporarily needed in some driver internal
  waiting code

- Remove private put_char method that does a write call for one char - we
  have that anyway

- Most but not yet all of the termios copy under lock fixing (some has other
  dependencies to follow)

- Note a few locking bugs in drivers found in the process

- Kill remaining [ab]users of TIOCG/SSOFTCAR in the driver, these must go to
  fix the termios locking

epca: lock_kernel push down

2008-04-30T15:29:38+00:00

Prepare epca for removing the lock from above. Most of epca is internally
locked so we can trivially push it down to a few bits of code. Drop the TIOCG/SSOFTCAR handling as that is done *properly* with locks by the mid layer.
