13 Handheld devices from One Netbook and Aya Neo provide fan readings and fan
14 control through their embedded controllers.
16 Currently only supports AMD boards from One X Player, AOK ZOE, and some Aya
17 Neo devices. One X Player Intel boards could be supported if we could figure
18 out the EC registers and values to write to since the EC layout and model is
19 different. Aya Neo devices preceding the AIR may not be supportable as the EC
20 model is different and do not appear to have manual control capabilities.
22 Some models have a toggle for changing the behaviour of the "Turbo/Silent"
23 button of the device. It will change the key event that it triggers with
24 a flip of the `tt_toggle` attribute. See below for boards that support this
30 Currently the driver supports the following handhelds:
40 - OneXPlayer mini AMD PRO
42 "Turbo/Silent" button behaviour toggle is only supported on:
45 - OneXPlayer mini AMD (only with updated alpha BIOS)
46 - OneXPlayer mini AMD PRO
51 The following attributes are supported:
54 Read Only. Reads current fan RMP.
57 Read Write. Enable manual fan control. Write "1" to set to manual, write "0"
58 to let the EC control de fan speed. Read this attribute to see current status.
61 Read Write. Read this attribute to see current duty cycle in the range [0-255].
62 When pwm1_enable is set to "1" (manual) write any value in the range [0-255]
66 Read Write. Read this attribute to check the status of the turbo/silent
67 button behaviour function. Write "1" to activate the switch and "0" to
68 deactivate it. The specific keycodes and behaviour is specific to the device
69 both with this function on and off. This attribute is attached to the platform
70 driver and not to the hwmon driver (/sys/devices/platform/oxp-platform/tt_toggle)
