From mboxrd@z Thu Jan 1 00:00:00 1970 From: Geert Uytterhoeven Subject: [PATCH/RFC] gpio: em: Use dynamic allocation of GPIOs Date: Mon, 17 Nov 2014 15:30:32 +0100 Message-ID: <1416234632-16166-1-git-send-email-geert+renesas@glider.be> Return-path: Sender: linux-sh-owner@vger.kernel.org To: Magnus Damm , Linus Walleij , Alexandre Courbot Cc: linux-gpio@vger.kernel.org, devicetree@vger.kernel.org, linux-sh@vger.kernel.org, Geert Uytterhoeven List-Id: devicetree@vger.kernel.org Use dynamic allocation of GPIOs instead of looking at the gpio%u alias in DT. --- - Is this correct? Not having to care about the alias would simplify the to-be-written DT binding documentation. - Completely untested.
