Subject: [PATCH 1/4] gpio_keys: detect keys pressed before booting.
Date: Mon, 11 Mar 2013 00:36:04 +0100 [thread overview]
Message-ID: <1362958567-6110-2-git-send-email-vicencb@gmail.com> (raw)
In-Reply-To: <1362958567-6110-1-git-send-email-vicencb@gmail.com>
If a key is pressed but not released before booting and the key is
connected to an active low gpio it's not detected. This patch solves
that.
