Apple SMC driver (hardware monitoring and control)

This driver provides support for the Apple System Management Controller, which
provides an accelerometer (Apple Sudden Motion Sensor), light sensors,
temperature sensors, keyboard backlight control and fan control. Only
Intel-based Apple's computers are supported (MacBook Pro, MacBook, MacMini).
