Input: psmouse - add support for Cortron PS/2 Trackballs
Cortron PS/2 Trackballs (700-0001A) report the 4th button using the 4th bit of the first packet (yes, it breaks the standard PS/2 protocol). This patch adds an extra protocol to generate BTN_SIDE based on the 4th bit. There's no way to detect those trackballs using any kind of special sequence, thus the protocol must be activated explicitely by writing into 'protocol' sysfs attribute: echo -n "cortps" > /sys/devices/platform/i8042/serio1/protocol Signed-off-by: Aristeu Rozanski <arozansk@redhat.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
