Subject: [PATCH v2 3/6] ARM: dts: sun9i: Enable i2c3 on A80 Optimus board
Date: Fri, 31 Oct 2014 11:05:48 +0800 [thread overview]
Message-ID: <1414724751-25580-4-git-send-email-wens@csie.org> (raw)
In-Reply-To: <1414724751-25580-1-git-send-email-wens@csie.org>
i2c3 is exposed on the GPIO extension header. Enable it so we can use it.
Also enable internal pull-ups on the pins, as they don't seem to have
external pull-up resistors.
