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.
Currently the driver supports the following handhelds:

The following attributes are supported:

pwm1_enable Read Write. Enable manual fan control. Write "1" to set to manual, write "0" to let the EC control de fan speed. Read this attribute to see current status.
pwm1 Read Write. Read this attribute to see current duty cycle in the range [0-255]. When pwm1_enable is set to "1" (manual) write any value in the range [0-255] to set fan speed.
tt_toggle Read Write. Read this attribute to check the status of the turbo/silent button behaviour function. Write "1" to activate the switch and "0" to deactivate it.
