Subject: [Bug 213579] Clevo NH55HJ (intel tigerlake) touchpad support (GPIO can't be used as IRQ)
Date: Thu, 22 Jul 2021 13:30:42 +0000 [thread overview]
Message-ID: <bug-213579-215701-s1Bq1NrXAv@https.bugzilla.kernel.org/> (raw)

--- Comment #38 from wse@tuxedocomputers.com ---
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
