* tty_port: Add a port level carrier detect operationAlan Cox2009-01-021-5/+21
| | | | | | | | This is the first step to generalising the various pieces of waiting logic duplicated in all sorts of serial drivers. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* char: moxa.c sparse annotationHarvey Harrison2008-10-161-1/+1
| | | | | | | | | | | The only use is to pass this to le16_to_cpu, declare as such drivers/char/moxa.c:548:11: warning: cast to restricted __le16.

* tty: kref usage for isicom and moxaAlan Cox2008-10-131-23/+38
| | | | | | | | | | Rather than blindly keep taking krefs we reorder the code in a few places to pass the tty down to the right place (which is important as from the user side it is not the case that tty == port->tty in all situations). For the irq and related paths use the krefs to stop the tty being freed under us. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* tty: rework break handlingAlan Cox2008-07-221-1/+2
| | | | | | | | | Some hardware needs to do break handling itself and may have partial support only. Make break_ctl return an error code. Add a tty driver flag so you can indicate driver hardware side break support. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | | | Simple search/replace except for synclink.c where I noticed a real bug and fixed it too. It was doing NULL + offset, then checking for NULL if the remap failed.

* tty/serial: lay the foundations for the next set of reworksAlan Cox2008-04-301-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | - 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 Signed-off-by: Alan Cox <alan@redhat.com> Cc: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
