23	  This driver adds support for the ACPI-WMI (Windows Management

25
26	  ACPI-WMI is a proprietary extension to ACPI to expose parts of the
27	  ACPI firmware to userspace - this is done through various vendor
28	  defined methods and data blocks in a PNP0C14 device, which are then
29	  made available for userspace to call.
30
31	  The implementation of this in Linux currently only exposes this to
32	  other kernel space drivers.
33
34	  This driver is a required dependency to build the firmware specific
35	  drivers needed on many machines, including Acer and HP laptops.
