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