From mboxrd@z Thu Jan 1 00:00:00 1970 From: Linus Walleij Subject: [PATCH 1/5] pinctrl: Add DT bindings for Cortina Gemini Date: Sat, 15 Jul 2017 19:50:52 +0200 Message-ID: <20170715175056.13040-1-linus.walleij@linaro.org> Return-path: Sender: devicetree-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: linux-gpio-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Hans Ulli Kroll , Florian Fainelli Cc: Janos Laube , Paulius Zaleckas , linux-arm-kernel-IAPFreCvJWM7uuMidbF8XUB+6BGkLq7r@public.gmane.org, Linus Walleij , devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-Id: devicetree@vger.kernel.org The Cortina Gemini pin controller uses the standard pin control bindings for muxing functions with groups so these bindings should be entirely uncontroversial.
