Add documentation for admins regarding Uniwill laptops. This should
help them to setup the uniwill-laptop driver, which sadly cannot be
loaded automatically.

+Uniwill laptop extra features
+=============================
+
+On laptops manufactured by Uniwill (either directly or as ODM), the ``uniwill-laptop`` driver
+handles various platform-specific features.
+
+Module Loading
+--------------
+
+The ``uniwill-laptop`` driver relies on a DMI table to automatically load on supported devices.
+When using the ``force`` module parameter, this DMI check will be omitted, allowing the driver
+to be loaded on unsupported devices for testing purposes.
+
+Hotkeys
+-------
+
+Usually the FN keys work without a special driver. However as soon as the ``uniwill-laptop`` driver
+is loaded, the FN keys need to be handled manually. This is done automatically by the driver itself.
+
+Keyboard settings
+-----------------
+
+The ``uniwill-laptop`` driver allows the user to enable/disable:
+
+ - the FN and super key lock functionality of the integrated keyboard
+ - the touchpad toggle functionality of the integrated touchpad
+
+See Documentation/ABI/testing/sysfs-driver-uniwill-laptop for details.
+
+Hwmon interface
+---------------
+
+The ``uniwill-laptop`` driver supports reading of the CPU and GPU temperature and supports up to
+two fans. Userspace applications can access sensor readings over the hwmon sysfs interface.
+
+Platform profile
+----------------
+
+Support for changing the platform performance mode is currently not implemented.
+
+Battery Charging Control
+------------------------
+
+The ``uniwill-laptop`` driver supports controlling the battery charge limit. This happens over
+the standard ``charge_control_end_threshold`` power supply sysfs attribute. All values
+between 1 and 100 percent are supported.
+
+Additionally the driver signals the presence of battery charging issues through the standard
+``health`` power supply sysfs attribute.
+
+Lightbar
+--------
+
+The ``uniwill-laptop`` driver exposes the lightbar found on some models as a standard multicolor
+LED class device. The default name of this LED class device is ``uniwill:multicolor:status``.
+
+See Documentation/ABI/testing/sysfs-driver-uniwill-laptop for details on how to control the various
+animation modes of the lightbar.
