Subject: [PATCH resend 3/3] gpiolib: acpi: Add quirk to ignore EC gpio wakeups for 1 more HP x2 10 model
Date: Tue, 25 Feb 2020 11:27:53 +0100	[thread overview]
Message-ID: <20200225102753.8351-4-hdegoede@redhat.com> (raw)
In-Reply-To: <20200225102753.8351-1-hdegoede@redhat.com>

There are at least 3 variants of the HP x2 10 models:

Bay Trail SoC + AXP288 PMIC
Cherry Trail SoC + AXP288 PMIC
Cherry Trail SoC + TI PMIC

Like on the Bay Trail + AXP288 PMIC model, we also need to ignore wakeups
for the GPIO which is (ab)used for embedded-controller events on the
Cherry Trail + AXP288 PMIC model.

Fixes: aa23ca3d98f7 ("gpiolib: acpi: Add honor_wakeup module-option + quirk mech
