From dc5dfab4ed18f0756f304dc5699b5743ddf56f90 Mon Sep 17 00:00:00 2001
From: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com>
Date: Tue, 25 Feb 2014 15:59:19 +0400
Subject: [PATCH] ARM: pxa: add gpio keys information
Switching from corgikbd to matrixkbd corgi has lost support for few switches.
Readd them through gpio-keys-polled device (-polled, since scoop does
not provide IRQ for GPIO).
