Subject: input: bcm5974: Add quad-finger tapping
From: "Henrik Rydberg" <rydberg@xxxxxxxxxxx>
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.
