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