   4 Subject: [PATCH 1/1] Add gpio_mouse board setup to atstk1000 board
   5
   6 This patch adds a gpio_mouse_platform_data to the atstk1000 board code and
   7 registers a gpio_mouse platform_device. This will enable a GPIO mouse on header
   8 J1 on GPIO of the ATSTK1000 development kit. The board code is enabled/disabled
   9 in menuconfig.
  10
  11 By connecting J1 (GPIO) to J25 (SWITCH) you can use the following keys to
  12 simulate a mouse:
  13
  14 SW0: right
  15 SW1: down
  16 SW2: up
  17 SW3: left
  18 SW5: right button
  19 SW6: middle button
  20 SW7: left button
