- * In all Intel-based Apple hardware there is an SMC chip to control the
- * backlight, fans and several other generic device parameters. It also
- * contains the magic keys used to dongle Mac OS X to the device.
- *
- * This driver was mostly created by looking at the Linux AppleSMC driver
- * implementation and does not support IRQ.
