From da91ece226729c76f60708efc275ebd4716ad089 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Thu, 1 Apr 2021 18:27:40 +0200 Subject: [PATCH] gpiolib: acpi: Add quirk to ignore EC wakeups on Dell Venue 10 Pro 5055 Like some other Bay and Cherry Trail SoC based devices the Dell Venue 10 Pro 5055 has an embedded-controller which uses ACPI GPIO events to report events instead of using the standard ACPI EC interface for this. The EC interrupt is only used to report battery-level changes and it keeps doing this while the system is suspended, causing the system to not stay suspended. Add an ignore-wake quirk for the GPIO pin used by the EC to fix the spurious wakeups from suspend.
