Subject: input: bcm5974: Add support for the Macbook 5 (Unibody)
From: "Henrik Rydberg" <rydberg@xxxxxxxxxxx>
Add support for the new unibody Macbook, with physically integrated button
and trackpad. A new button, BTN_TOOL_PRESS, is introduced to allow for
non-trivial handling of this device in user space.
