10Description:
11------------
12
13Handheld devices from One Netbook and Aya Neo provide fan readings and fan
14control through their embedded controllers.
15
16Currently only supports AMD boards from One X Player, AOK ZOE, and some Aya
17Neo devices. One X Player Intel boards could be supported if we could figure
18out the EC registers and values to write to since the EC layout and model is
19different. Aya Neo devices preceding the AIR may not be supportable as the EC
20model is different and do not appear to have manual control capabilities.
