From 6916d97f6e25cc66a32d6e9a16419067d843b14f Mon Sep 17 00:00:00 2001 From: Henrik Rydberg Date: Mon, 27 Apr 2009 11:52:43 -0700 Subject: 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.
