Description:
------------
Handheld devices from OneNetbook, AOKZOE, AYANEO, And OrangePi provide fan
readings and fan control through their embedded controllers.
Currently supports OneXPlayer devices, AOKZOE, AYANEO, and OrangePi
handheld devices. AYANEO devices preceding the AIR and OneXPlayer devices
preceding the Mini A07 are not supportable as the EC model is different
and do not have manual control capabilities.
Some OneXPlayer and AOKZOE models have a toggle for changing the behaviour
of the "Turbo/Silent" button of the device. It will change the key event
that it triggers with a flip of the `tt_toggle` attribute. See below for
boards that support this function.
