31 * Driver for extra ACPI-controlled features found on HP laptops
32 * that use a WMI enabled BIOS (e.g. HP Compaq 8510p and 6510p).
33 * Allows to control and read status of integrated hardware and read
34 * BIOS settings through CMI.
35 * Inspired by the hp-wmi driver, which implements a subset of these
36 * features (hotkeys) on Linux.
