Hmm, this is weird. I tried to apply the 2 patches of this series to a
4.0 fedora kernel[1], and the touch{pad|screen} are desperately muted.
The abs_X/Y max shows up as 0, so there is something wrong with either
my touchpad (which works fine on ChromeOS) or with the driver.
There are no differences between 4.0-rcX and the final 4.0 so I suspect
there must be something else.
I also copied the 2 samus-* config files from the ChromeOS root to
/lib/firmware but this does not change anything.
In [3], I enabled the debug output of atmel_mxt, and it seems that the
table of functions is missing the T9 one, which is the multitouch one... :(
Any help would be greatly appreciated so we can fix [2] and support
those laptops in Fedora directly.
Cheers,
Benjamin
