From cd5bca6f627442b63012ac0cafc6452bc929832e Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Fri, 26 Dec 2014 14:53:13 -0600 Subject: [PATCH] ARM: dts: am437x-idk: add gpio-based power key 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.
