>From 9c5fa914202d20756c56e0c4fd76035ed8f8ced8 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/1] Add gpio_mouse board setup to atstk1000 board
This patch adds a gpio_mouse_platform_data to the atstk1000 board code and
registers a gpio_mouse platform_device. This will enable a GPIO mouse on header
J1 on GPIO of the ATSTK1000 development kit. The board code is enabled/disabled
in menuconfig.
By connecting J1 (GPIO) to J25 (SWITCH) you can use the following keys to
simulate a mouse:
SW0: right
SW1: down
SW2: up
SW3: left
SW5: right button
SW6: middle button
SW7: left button
