Subject: [PATCH] gpiolib: acpi: Add a ignore wakeup quirk for Clevo NL5xNU
Date: Wed, 22 Mar 2023 13:15:47 +0100 [thread overview]
Message-ID: <20230322121547.14997-1-wse@tuxedocomputers.com> (raw)
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 NL5xNU there is a mistake in the ACPI tables that the
TP_ATTN# signal connected to GPIO 9 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 9.
This patch is analoge to a very similar patch for NL5xRU, just the DMI
string changed.
