46 * SNY5001
47 *   This is the ACPI handle for the "Sony Notebook Control" driver under
48 *   Windows.
49 *   It provides several methods within the ACPI namespace, including:
50 *  [GS]BRT [GS]PBR [GS]CTR [GS]PCR [GS]CMI [CDPW GCDP]? GWDP PWAK PWRN
51 *
52 * SNY6001
53 *   This is the ACPI handle for the "Sony Programmable I/O" driver under
54 *   Windows.
55 *   It is not yet supported by this driver, but provides control over the
56 *   power to the bluetooth, built-in camera and HSDPA modem devices in some
57 *   laptops, and also allows some control of the fan speed.
