From 2c6e0277e1eab3df5db81c59e408b7b1c14b1b72 Mon Sep 17 00:00:00 2001 From: Seth Forshee Date: Wed, 11 Mar 2015 17:26:41 -0500 Subject: HID: multitouch: Add support for button type usage According to [1], Windows Precision Touchpad devices must supply a button type usage in the device capabilities feature report. A value of 0 indicates that the device contains a depressible button (i.e. it's a click-pad) whereas a value of 1 indicates a non-depressible button. Add support for this usage and set INPUT_PROP_BUTTONPAD on the touchpad input device whenever a depressible button is present.
