25 This is a replacement for the following in-kernel drivers:
26 1) gpio_keys (KEYBOARD_GPIO)
27 2) gpio_keys_polled (KEYBOARD_GPIO_POLLED)
29 Instead of generating input events (like in-kernel drivers do) it generates
30 uevent-s and broadcasts them. This allows disabling input subsystem which is
31 an overkill for OpenWrt simple needs.
