| | | | | | | | | | | | | | | | | | | | We don't actually need this and it causes problems for internal use of this functionality. Currently there is a single use of the FILE * pointer. That is the serial core which uses it to check tty_hung_up_p. However if that is true then IO_ERROR is also already set so the check may be removed.

| | | | | | | | | | | | | | | {read,write}_mos_reg No functionality added or bugs fixed, just improved code consistency and (hopefully) readability by replacing send_mos_cmd with the register read & write functions that were used for parallel port registers.

* USB: usbserial: mos7720: add support for parallel port on moschip 7715Mike Dunn2010-05-201-86/+720
| | | | | | | | | | | | | | | Add support for the parallel port on the moschip MCS7715 device. The port registers itself with the parport subsystem as a low-level driver. A separate entry to the kernel configuration is added beneath that for the mos7720, to avoid the need to link with the parport subsystem code for users who don't have or don't want the parallel port. Only compatibility mode is currently supported (no ECP/EPP). Tested with both moschip devices (7720 and 7715) on UP and SMP hosts, including regression testing of serial port, concurrent operation of serial and parallel ports, and various connect / disconnect scenarios.

* USB: serial: add support for serial port on the moschip 7715Mike Dunn2010-03-021-4/+130
| | | | | | | | | | | | | | | | | Add support for the serial port on devices based on the MosChip 7715, which provides a serial and parallel port on a single usb interface. This is added to the existing driver for the Moschip 7720 dual serial port device. The 7715 is very similiar to the 7720, requiring only the addition of a calc_num_ports() function, a separate interrupt-in endpoint callback, and some manipulation of the port pointers added to the attach() function to correct the fact that the usbserial core erroneously assigns the first bulk in/out endpoint pair to the serial port (the 7715 uses these for its parallel port). There is no support for the 7715's parallel port yet. Signed-off-by: Mike Dunn <mikedunn@newsguy.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* USB: usb-serial: replace shutdown with disconnect, releaseAlan Stern2009-06-151-6/+3
| | | | | | | | | | | | | | | | This patch (as1254) splits up the shutdown method of usb_serial_driver into a disconnect and a release method. The problem is that the usb-serial core was calling shutdown during disconnect handling, but drivers didn't expect it to be called until after all the open file references had been closed. The result was an oops when the close method tried to use memory that had been deallocated by shutdown.

| | | | | | | | | | | | | Use kref in the USB serial drivers so that we don't free tty structures from under the URB receive handlers as has historically been the case if you were unlucky.

* usb_serial: API all changeAlan Cox2008-07-221-52/+35
| | | | | | | | | | | | | | | | | | | USB serial likes to use port->tty back pointers for the real work it does and to do so without any actual locking. Unfortunately when you consider hangup events, hangup/parallel reopen or even worse hangup followed by parallel close events the tty->port and port->tty pointers are not guaranteed to be the same as port->tty is the active tty while tty->port is the port the tty may or may not still be attached to. So rework the entire API to pass the tty struct. For console cases we need to pass both for now. This shows up multiple drivers that immediately crash with USB console some of which have been fixed in the process. Longer term we need a proper tty as console abstraction Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | | This fixes a problem where the mos7720 driver will make io to a device from which it has been logically disconnected.
