This patch adds support for the TM2 touch key and led functionlity. The driver interfaces with userspace through an input device and reports KEY_PHONE and KEY_BACK event types. LED brightness can be controlled by "/sys/class/leds/tm2-touchkey/brightness".

This sentence needs improvements. How about just: "Beside input device, this driver provides also brightness control for LEDs on touch keys." Best regards, Krzysztof
