From 158e928741e58eb4aa379da422290c10fef23f00 Mon Sep 17 00:00:00 2001 From: Henrik Rydberg Date: Tue, 28 Apr 2009 07:03:54 -0700 Subject: Input: bcm5974 - Add support for the Macbook 5 (Unibody) This patch adds support for the new unibody Macbook, with physically integrated button and trackpad. Since the integrated button changes the logic for touch-and-click, a device capability bit mask is now reported in input_id.version, which can be picked up by user space via a EVIOCGID call.
