Subject: [PATCH v3 6/6] arm64: tegra: Enable gpio-keys on Jetson AGX Orin Developer Kit
Date: Wed, 8 Dec 2021 18:30:47 +0100 [thread overview]
Message-ID: <20211208173047.558108-6-thierry.reding@gmail.com> (raw)
In-Reply-To: <20211208173047.558108-1-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
Expose power, force-recovery and sleep buttons via a gpio-keys device so
that userspace can receive events from them.
