Clock Generators
The clock generator is expected to provide the frequencies shown in
Clock Control Signals from Intel
Synthesizer (Mobile/Ultra Mobile Only)
The clock generator is assumed to have a direct connection from the following ICH7
signals:

PCI Clock to ICH7. This is not the system PCI clock.
This clock must keep running in S0 while the system
PCI clock may stop based on CLKRUN# protocol.
Stopped in S3 ~ S5 based on SLP_S3# assertion.
Used by USB controllers and Intel
Audio controller. Stopped in S3 ~ S5 based on
SLP_S3# assertion.
Used by ACPI timers. Stopped in S3 ~ S5 based on
