- * HCI is Toshiba's "Hardware Control Interface" which is supposed to

- * dedicated ACPI methods instead of using this primitive interface.
- * However the ACPI methods seem to be incomplete in some areas (for
- * example they allow setting, but not reading, the LCD brightness value),
- * so this is still useful.
