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
|
|
