This mini-driver drives the SNC and SPIC device present in the ACPI BIOS of the

Sony Vaio laptops. This driver mixes both devices functions under the same

(hopefully consistent) interface. This also means that the sonypi driver is

obsoleted by sony-laptop now.



It gives access to some extra laptop functionalities. In its current

form, this driver let the user set or query the screen brightness

through the backlight subsystem and remove/apply power to some devices.

Fn keys (hotkeys):

Some models report hotkeys through the SNC or SPIC devices, such events are

reported both through the ACPI subsystem as acpi events and through the INPUT

subsystem. See the logs of acpid or /proc/acpi/event and

devices are created by the driver.
