12	Description
13	-----------
14	
15	This driver implements support for the IDT ICS932S401 chip family.
16	
17	This chip has 4 clock outputs--a base clock for the CPU (which is likely
18	multiplied to get the real CPU clock), a system clock, a PCI clock, a USB
19	clock, and a reference clock.  The driver reports selected and actual
20	frequency.  If spread spectrum mode is enabled, the driver also reports by what
21	percent the clock signal is being spread, which should be between 0 and -0.5%.
22	All frequencies are reported in KHz.
23	
24	The ICS932S401 monitors all inputs continuously. The driver will not read
25	the registers more often than once every other second.
26	
27	Special Features
28	----------------
29	
30	The clocks could be reprogrammed to increase system speed.  I will not help you
31	do this, as you risk damaging your system!
