[PATCH] gpiolib: acpi: Add a ignore wakeup quirk for Clevo NH5xAx

From: Werner Sembach
Date: Fri Feb 10 2023 - 11:46:49 EST


commit 1796f808e4bb ("HID: i2c-hid: acpi: Stop setting wakeup_capable")
changed the policy such that I2C touchpads may be able to wake up the
system by default if the system is configured as such.

However on Clevo NH5xAx/TUXEDO XA15 Gen10 there is a mistake in the ACPI
tables that the TP_ATTN# signal connected to GPIO 10 is configured as
ActiveLow and level triggered but connected to a pull up. As soon as the
system suspends the touchpad loses power and then the system wakes up.

To avoid this problem, introduce a quirk for this model that will prevent
the wakeup capability for being set for GPIO 10.
