Subject: [PATCH 3/4] ARM: dts: aspeed: bletchley: bind presence-sledX pins via gpio-keys
Date:   Mon, 13 Jun 2022 17:51:49 +0800
Message-Id: <20220613095150.21917-4-potin.lai.pt@gmail.com>
In-Reply-To: <20220613095150.21917-1-potin.lai.pt@gmail.com>
References: <20220613095150.21917-1-potin.lai.pt@gmail.com>
Precedence: bulk

Bind presence-sledX pins via gpio-keys driver to monitor and export
GPIO pin values on DBUS using phosphor-gpio-presence service.
