From 3631c597ca33df06610a5482447912d36d0a9ff2 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Tue, 1 Mar 2016 08:14:02 +0100 Subject: [PATCH] ARM: dts: imx53-qsb: Fix gpio button polarity The polarity of the gpio buttons is defined to '0' which is active high. The buttons are active low though which has been verified by testing it and by looking into the schematics. While at it use defines rathers than numbers for the key codes.
