* This is the power management code for ATI radeon chipsets. It contains
* some dynamic clock PM enable/disable code similar to what X.org does,
* some D2-state (APM-style) sleep/wakeup code for use on some PowerMacs,
* and the necessary bits to re-initialize from scratch a few chips found
* on PowerMacs as well. The later could be extended to more platforms
* provided the memory controller configuration code be made more generic,
* and you can get the proper mode register commands for your RAMs.
* Those things may be found in the BIOS image...
