374b4f9fe12SLen Brown	  This driver adds support for the ACPI-WMI (Windows Management

376b4f9fe12SLen Brown
377b4f9fe12SLen Brown	  ACPI-WMI is a proprietary extension to ACPI to expose parts of the
378b4f9fe12SLen Brown	  ACPI firmware to userspace - this is done through various vendor
379b4f9fe12SLen Brown	  defined methods and data blocks in a PNP0C14 device, which are then
380b4f9fe12SLen Brown	  made available for userspace to call.
381b4f9fe12SLen Brown
382b4f9fe12SLen Brown	  The implementation of this in Linux currently only exposes this to
383b4f9fe12SLen Brown	  other kernel space drivers.
384b4f9fe12SLen Brown
385b4f9fe12SLen Brown	  This driver is a required dependency to build the firmware specific

402b4f9fe12SLen Brown	  and most importantly, allows you to blink those fancy LEDs intended
