Input: serio - add support for PS2Mult multiplexer protocol

2010-10-18T16:33:31+00:00

PS2Mult is a simple serial protocol used for multiplexing several PS/2
streams into one serial data stream. It's used e.g. on TQM85xx series
of boards.

Input: serio - support multiple child devices per single parent

2010-10-13T14:49:28+00:00

Some (rare) serio devices need to have multiple serio children. One of
the examples is PS/2 multiplexer present on several TQC STKxxx boards,
which connect PS/2 keyboard and mouse to single tty port.

No need to keep track of it by ourselves.

Input: serio - fix potential deadlock when unbinding drivers

2010-01-06T08:14:32+00:00

sysfs_remove_group() waits for sysfs attributes to be removed, therefore
we do not need to worry about driver-specific attributes being accessed
after driver has been detached from the device. In fact, attempts to take
serio->drv_mutex in attribute methods may lead to the following deadlock:

                                          sysfs_read_file()
                                            fill_read_buffer()
                                              sysfs_get_active_two()
                                                psmouse_attr_show_helper()
                                                  serio_pin_driver()
serio_disconnect_driver()
  mutex_lock(&serio->drv_mutex);
                                <-------->        mutex_lock(&serio_drv_mutex);
    psmouse_disconnect()
      sysfs_remove_group(... psmouse_attr_group);
        ....
        sysfs_deactivate();
          wait_for_completion();

Fix this by removing calls to serio_[un]pin_driver() and functions themselves
and using driver-private mutexes to serialize access to attribute's set()
methods that may change device state.

Input: add driver for Dynapro serial touchscreen

2009-10-26T18:01:30+00:00

This is a driver for Dynapro serial touchscreen, which used to be
supported in Xorg. The driver needs updated inputattach utility to
initialize serial port and create proper serio device before the
driver will be bound to it.
