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

+
+	  ACPI-WMI is a proprietary extension to ACPI to expose parts of the

+	  defined methods and data blocks in a PNP0C14 device, which are then
+	  made available for userspace to call.
+
+	  The implementation of this in Linux currently only exposes this to
+	  other kernel space drivers.
+
+	  This driver is a required dependency to build the firmware specific
+	  drivers needed on many machines, including Acer and HP laptops.

+ * This driver has been reverse-engineered by parsing the DSDT of the Surface 3
+ * and looking at the registers of the chips.
+ *
+ * The DSDT allowed to find out that:
+ * - the driver is required for the ACPI BAT0 device to communicate to the chip
+ *   through an operation region.
+ * - the various defines for the operation region functions to communicate with
+ *   this driver
+ * - the DSM 3f99e367-6220-4955-8b0f-06ef2ae79412 allows to trigger ACPI
+ *   events to BAT0 (the code is all available in the DSDT).
+ *
+ * Further findings regarding the 2 chips declared in the MSHW0011 are:
+ * - there are 2 chips declared:
+ *   . 0x22 seems to control the ADP1 line status (and probably the charger)
+ *   . 0x55 controls the battery directly
+ * - the battery chip uses a SMBus protocol (using plain SMBus allows non
+ *   destructive commands):
+ *   . the commands/registers used are in the range 0x00..0x7F
+ *   . if bit 8 (0x80) is set in the SMBus command, the returned value is the
+ *     same as when it is not set. There is a high chance this bit is the
+ *     read/write
+ *   . the various registers semantic as been deduced by observing the register
+ *     dumps.
