From 5c6db1a421c6ceef199a956c7e0c1244ea6dfef7 Mon Sep 17 00:00:00 2001 From: Simon Horman Date: Tue, 30 Jul 2013 10:59:00 +0900 Subject: [PATCH] ARM: shmobile: ape6evm: support GPIO switches The ape6evm board has switches S16 - S23 wired up to GPIO pins. This patch allows access to those pins as gpio-keys.
