Subject: [PATCH 04/12] ARM: dts: sun8i: Add pin muxing option for R_UART
Date: Sun, 17 Aug 2014 11:52:10 +0800	[thread overview]
Message-ID: <1408247538-16950-5-git-send-email-wens@csie.org> (raw)
In-Reply-To: <1408247538-16950-1-git-send-email-wens@csie.org>

R_UART is available on extra pads on certain tablets, which makes it
ideal for use as a console. Here we add the pins for it.
