0017 Description
0018 -----------
0019
0020 This driver implements support for the IDT ICS932S401 chip family.
0021
0022 This chip has 4 clock outputs--a base clock for the CPU (which is likely
0023 multiplied to get the real CPU clock), a system clock, a PCI clock, a USB
0024 clock, and a reference clock. The driver reports selected and actual
0025 frequency. If spread spectrum mode is enabled, the driver also reports by what
0026 percent the clock signal is being spread, which should be between 0 and -0.5%.
0027 All frequencies are reported in KHz.
0028
0029 The ICS932S401 monitors all inputs continuously. The driver will not read
0030 the registers more often than once every other second.

0035 The clocks could be reprogrammed to increase system speed. I will not help you
0036 do this, as you risk damaging your system!
