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