From mboxrd@z Thu Jan 1 00:00:00 1970 From: Felipe Balbi Subject: [PATCH] arm: boot: dts: am437x-idk: add gpio-based power key Date: Fri, 26 Dec 2014 14:35:16 -0600 Message-ID: <1419626116-12833-1-git-send-email-balbi@ti.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-omap-owner@vger.kernel.org To: Tony Lindgren Cc: Linux OMAP Mailing List , Linux ARM Kernel Mailing List , devicetree@vger.kernel.org, Felipe Balbi List-Id: devicetree@vger.kernel.org AM437x IDK board has a User Switch which we can program to whatever we want. Because this board doesn't have a PMIC which can give us power button presses, let's use this user switch as a gpio-keys power button. Signed-off-by: Felipe Balbi --- depends on [1]. Boot logs at [2]. Note that this can rather easily be folded into the original patch if so desired.
