[PATCH] USB: add apple usb touchpad driver
This is a driver for the USB touchpad which can be found on post-February 2005
Apple PowerBooks.
This driver is derived from Johannes Berg's appletrackpad driver [1],
but it has been improved in some areas:
* appletouch is a full kernel driver, no userspace program is necessary
* appletouch can be interfaced with the synaptics X11 driver[2], in order
to have touchpad acceleration, scrolling, two/three finger tap, etc.
This driver has been tested by the readers of the 'debian-powerpc' mailing
list for a few weeks now and I believe it is now ready for inclusion into the
mainline kernel.
Credits go to Johannes Berg for reverse-engineering the touchpad protocol,
Frank Arnold for further improvements, and Alex Harper for some additional
information about the inner workings of the touchpad sensors.
