Subject: [PATCH] ARM: imx/iomux-v3: allow pad_list to be const
Message-ID: <1344527835-32567-1-git-send-email-u.kleine-koenig@pengutronix.de>
To: linux-arm-kernel@lists.infradead.org
List-Id: linux-arm-kernel.lists.infradead.org

Also fix all machine files to make use of it and while at it also make
the pad lists __init_const.

Hello,

well, iomux-v3 is dying so I don't know how welcome this patch is.

Best regards
Uwe
