Hi, I think what you'll need to do is add a new GPIO Keypad device. For reference, check out the omap kernel source, and take a look at arch/arm/mach-omap2/board-tuna-input.c, where they are using GPIO lines for KEY_POWER, KEY_VOLUMEDOWN, and KEY_VOLUMEUP.
You can also refer to include/linux/gpio_event.h and drivers/input/misc/gpio_event.c. Alternatively, you can go the other route of using a gpio_keys device.
