73 * The Toshiba configuration interface is composed of the HCI and the SCI,
74 * which are defined as follows:
76 * HCI is Toshiba's "Hardware Control Interface" which is supposed to
77 * be uniform across all their models. Ideally we would just call
78 * dedicated ACPI methods instead of using this primitive interface.
79 * However the ACPI methods seem to be incomplete in some areas (for
80 * example they allow setting, but not reading, the LCD brightness value),
81 * so this is still useful.
83 * SCI stands for "System Configuration Interface" which aim is to
84 * conceal differences in hardware between different models.
