Input: bcm5974 - add quad-finger tapping
The integrated button on the new unibody Macbooks presents a need to report explicit four-finger actions. Evidently, the finger pressing the button is also touching the trackpad, so in order to fully support three-finger actions, the driver must be able to report four-finger actions. This patch adds a new button, BTN_TOOL_QUADTAP, which achieves this. Signed-off-by: Henrik Rydberg <rydberg@euromail.se> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
