Subject: [PATCH 0/8] Input: support for latest Lenovo thinkpads (series 80)

Hi Dmitry,

well, this year, Lenovo gave us a surprise and decided to not use
the same touchpad/trackstick in all its model. And by default, the
support under Linux is less than ideal.

Please find a series that should fix those issues. Compared to the 60
series, there do not seem to e BIOS table issues this time, and suspend/resume
works fine thanks to your latest trackstick fixes.

The T480s is a different beast, as it uses an Elan touchpad.
I have been carrying the patches 3-6 for a while and tested previous
versions on various Elan PS/2 hardware without an issue as far as I
could tell. I was lacking tests from users with SMBus as all the laptops
I tried where puer PS/2.

Anyway, it would be cool if you could have a look at the series.
