From mboxrd@z Thu Jan 1 00:00:00 1970 From: thomas.abraham@linaro.org (Thomas Abraham) Date: Wed, 06 Mar 2013 17:34:21 +0530 Subject: [PATCH] mmc: dwmmc: let device core setup the default pin configuration Message-ID: <1362571461-14570-1-git-send-email-thomas.abraham@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org With device core now able to setup the default pin configuration, the pin configuration code based on the deprecated Samsung specific gpio bindings is removed.
