Add support for the OrangePi NEO-01. It uses different registers for PWM manual mode, set PWM, and read fan speed than previous devices. Valid PWM input and duty cycle is 1-244, we scale this from 1-255 to maintain compatibility with the existing interface. Add OneXPlayer 2 series, OneXFly, and X1 series models. The 2/X1 series use new registers for turbo button takeover and read fan speed. X1 has an Intel variant so change the CPU detection at init to only check for the affected devices. While at it, adjust formatting of some constants and reorder all cases alphabetically for consistency. Rename OXP_OLD constants to OXP_MINI for disambiguation. Update code comments for clarity. Add support for AYANEO models 2S, AIR 1S, Flip series, GEEK 1S, and KUN. Signed-off-by: Derek J.

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.
