Subject: [PATCH 4/4] ARM: dts: imx: add alias for gpio
Date: Sun, 5 Aug 2012 14:01:28 +0800 [thread overview]
Message-ID: <1344146488-9496-4-git-send-email-shawn.guo@linaro.org> (raw)
In-Reply-To: <1344146488-9496-1-git-send-email-shawn.guo@linaro.org>
Add alias for gpio nodes, so that gpio driver can identify the port
number and then specify a sensible gpio base rather than using the
one dynamically allocated by gpio core.
Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
