  10 Description:
  11 ------------
  12
  13 Handheld devices from One Netbook and Aya Neo provide fan readings and fan
  14 control through their embedded controllers.
  15
  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.
