Subject: Input: add Synaptics USB device driver
|
||||||
|
|
||||||
|
commit 8491ee1093c476ea3a9a19ab8593d8531cab40f7 upstream.
|
||||||
|
|
||||||
|
This patch adds a driver for Synaptics USB touchpad or pointing stick
|
||||||
|
devices. These USB devices emulate an USB mouse by default, so one can
|
||||||
|
also use the usbhid driver. However, in combination with special user
|
||||||
|
space drivers this kernel driver allows one to customize the behaviour
|
||||||
|
of the device.
|
||||||
|
|
||||||
|
An extended version of this driver with support for the cPad background
|
||||||
|
display can be found at
|
||||||
|
<http://jan-steinhoff.de/linux/synaptics-usb.html>.
