Message-Id: <1412239220-22495-2-git-send-email-linus.walleij@linaro.org>
Date: Thu, 2 Oct 2014 10:40:14 +0200
From: Linus Walleij <linus.walleij@...aro.org>
To: linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org
Cc: linux-gpio@...r.kernel.org,
Linus Walleij <linus.walleij@...aro.org>
Subject: [PATCH 1/7] pinctrl: nomadik: force-convert to generic mux bindings
This converts the Nomadik pin controller and all associated device
trees to use the standard, generic mux bindings for pin controllers.
There are no such device trees deployed in the wild so this is
safe to do to set a good example.
Signed-off-by: Linus Walleij <linus.walleij@...aro.org>
