+ * 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.
