72 * The Toshiba configuration interface is composed of the HCI and the SCI,
258c5903 73 * which are defined as follows:

75 * HCI is Toshiba's "Hardware Control Interface" which is supposed to
76 * be uniform across all their models. Ideally we would just call
77 * dedicated ACPI methods instead of using this primitive interface.
78 * However the ACPI methods seem to be incomplete in some areas (for
79 * example they allow setting, but not reading, the LCD brightness value),
80 * so this is still useful.
