* i7300_idle driver v1.55Andy Henroid2008-10-213-0/+692
The Intel 7300 Memory Controller supports dynamic throttling of memory which can be used to save power when system is idle. This driver does the memory throttling when all CPUs are idle on such a system. Refer to "Intel 7300 Memory Controller Hub (MCH)" datasheet for the config space description.
