From c463eb62ac5bd8c26578cae42e1d5bb397aed100 Mon Sep 17 00:00:00 2001 From: Dmitry Artamonow Date: Fri, 27 Nov 2009 12:13:01 +0100 Subject: ARM: 5823/1: SA1100: h3100/h3600: add support for gpio-keys Add support for "Power" and "Action" (joystick center) buttons - the only buttons on iPaq h3100/h3600 connected to GPIOs (other buttons are controlled by microcontroller) Also remove setting PWER for wakeup on Power button press - gpio-keys driver will handle it.
