-From: Hans-Christian Egtvedt <hcegtvedt@atmel.com>
-Date: Mon, 6 Aug 2007 08:31:14 +0200
-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
-
-Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com>
