Dell ALPS patches for Dell Latitude 7250 & 7450

Commit Message

Hello,

now I found on Dell support website, that they also provide
psmouse/alps.c driver for new Dell Latitude 7250 & 7450 machines:
http://www.dell.com/support/home/gh/en/ghdhs1/Drivers/DriversDetails?driverId=N5V5D

It is again in Ubuntu support package and so users and developers
who do not use Ubuntu probably do not know about it...

Dell alps.c driver introduced ALPS protocol v8 and v9. I did not
found anything on linux-input ML about it, so to make sure that
support for new ALPS/Dell models for linux do not disappear I'm
sending diff against linux v3.14-rc1 version (which looks like to
be version of which Dell introduced they changes)...

Thanks for this and the other related mail. I also have an alps.c
directly from alps themselves which adds support for v8 and v9
protocols. The problem is that like with v7 the code is not really
in a state where we want to take it as is, e.g. it does clickpad
softbutton emulation in the kernel instead of leaving it to userspace.

I spend a considerable amount of time cleaning up the alps code itself
and then adding a cleaner version of the v7 code, we should do the same
for the v8 and v9 code probably but that requires someone with hardware
access so that we can actually test the end result.

Regards,

Hans

Ok. Hans, can you look at least on second one patch?
http://www.spinics.net/lists/linux-input/msg36554.html

This is a bit shorter patch and maybe easier to review and decide 
if is needed or not...

I think you no that particular bit of the code better then me know,
given the recent fixes you've been doing there. I think it is best
to not take that patch / hack until we actually have reports from
someone with a machine where such a fix is needed.

Hans
