13 Handheld devices from OneNetbook, AOKZOE, AYANEO, And OrangePi provide fan
14 readings and fan control through their embedded controllers.
16 Currently supports OneXPlayer devices, AOKZOE, AYANEO, and OrangePi
17 handheld devices. AYANEO devices preceding the AIR and OneXPlayer devices
18 preceding the Mini A07 are not supportable as the EC model is different
19 and do not have manual control capabilities.
21 Some OneXPlayer and AOKZOE models have a toggle for changing the behaviour
22 of the "Turbo/Silent" button of the device. It will change the key event
23 that it triggers with a flip of the `tt_toggle` attribute. See below for
24 boards that support this function.
29 Currently the driver supports the following handhelds:
37 - AYANEO AIR Plus (Mendocino)
48 - OneXPlayer mini AMD PRO
55 "Turbo/Silent" button behaviour toggle is only supported on:
60 - OneXPlayer mini AMD (only with updated alpha BIOS)
61 - OneXPlayer mini AMD PRO
70 The following attributes are supported:
73 Read Only. Reads current fan RPM.
76 Read Write. Enable manual fan control. Write "1" to set to manual, write "0"
77 to let the EC control de fan speed. Read this attribute to see current status.
80 Read Write. Read this attribute to see current duty cycle in the range [0-255].
81 When pwm1_enable is set to "1" (manual) write any value in the range [0-255]
85 Read Write. Read this attribute to check the status of the turbo/silent
86 button behaviour function. Write "1" to activate the switch and "0" to
87 deactivate it. The specific keycodes and behaviour is specific to the device
88 both with this function on and off. This attribute is attached to the platform
89 driver and not to the hwmon driver (/sys/devices/platform/oxp-platform/tt_toggle)
