Subject: [PATCH 09/11] PINCTRL: lantiq: add functionality to falcon_pinconf_dbg_show
Date: Fri, 1 Feb 2013 13:05:03 +0100 [thread overview]
Message-ID: <1359720305-31933-9-git-send-email-blogic@openwrt.org> (raw)
In-Reply-To: <1359720305-31933-1-git-send-email-blogic@openwrt.org>
The current code only has a stub for falcon_pinconf_dbg_show. This patch adds
proper functionality.
