--- Comment #38 from wse@xxxxxxxxxxxxxxxxxxx ---
a) CPU Pin 57 = GPIO Pin 44
b) CPU PIN 37 = GPIO PIN 140
I don't know where one can look up the mapping CPU Pin <> GPIO Pin, Andy
Shevchenko did.
Pin 37/140 is not choosen randomly, but it's the pin the touchpad interrupt
line is physically attached to on the mainboards of the Tongfang GMxTGxx and
the Clevo NH5xHP.
I found this out by looking up the schematics of the Clevo and the linux source
code: https://bugzilla.kernel.org/show_bug.cgi?id=213579#c28
