Hi Jiri,
Well, this work is _not_ for 3.14 (except maybe patch 1), especially since it is missing the biggest part where we enable the capabilities of Logitech devices.
Long story short: This work is based on the work I did back in Summer 2011. I worked at Logitech for a few weeks to show up a demo of a driver for the Logitech Wireless Touchpad. At that time, a first draft has been done, but due to a lack of resources, noone upstreamed it. Since then, the code marinated a little at Logitech and in the ChromeOS kernel tree, but nobody tried to push it upstream. So here I am, trying to push this stuff upstream.
I can not send the full series right now because I am lacking most of the testing hardware (I mean I only have the oldest Wireless Touchpad). Hopefully, I should receive some other soon, and I'll be able to send the second part then.
Now, let me roughly explain the patches: - patch 1 can be applied right now I think, but it's entirely up to you Jiri. This patch should fix the missing notifications with some USB 3.0 boards. - patches 2 to 5 allows to forward in both direction the proprietary protocol used by Logitech (HID++ [1]) between the driver and the hardware. - later patches will introduce a transport layer for HID++ and also a driver to support full multitouch on various Logitech touchpads.
Nestor, Andrew, feel free to add your "Signed-off-by" whereever you want, I lost a little bit the track of who added what.
Cheers, Benjamin
