From mboxrd@z Thu Jan 1 00:00:00 1970 From: Magnus Damm Date: Thu, 18 Aug 2011 05:44:25 +0000 Subject: [PATCH 03/07] ARM: mach-shmobile: Kota2 GPIO Keys support Message-Id: <20110818054425.23410.51390.sendpatchset@rxone.opensource.se> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-sh@vger.kernel.org From: Magnus Damm This patch ties in GPIO Keys support on the Kota2 board. For now the keys are used in polling mode, but after extending the sh73a0 PFC with IRQ support we should be able to switch to the IRQ driven driver.
