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