    platform/x86: Add Asus Wireless Radio Control driver · f6a6bbae
    João Paulo Rechi Vita authored
    Some Asus notebooks like the Asus E202SA and the Asus X555UB have a
    separate ACPI device for notifications from the airplane mode hotkey.
    This device is called "Wireless Radio Control" in Asus websites and ASHS
    in the DSDT, and its ACPI _HID is ATK4002 in the two models mentioned
    above.
    
    For these models, when the airplane mode hotkey (Fn+F2) is pressed, a
    query 0x0B is started in the Embedded Controller, and all this query does
    is a notify ASHS with the value 0x88 (for acpi_osi >= "Windows 2012"):
    
    	Scope (_SB.PCI0.SBRG.EC0)
    	{
    		(...)
    		Method (_Q0B, 0, NotSerialized)  // _Qxx: EC Query
    		{
    			If ((MSOS () >= OSW8))
    			{
    				Notify (ASHS, 0x88) // Device-Specific
    			}
    			Else
    			{
    				(...)
    			}
    		}
    	}
