|   | Kernel driver ics932s401 | ||
|  | ====================== | ||
|  | 
 | ||
|  | Supported chips: | ||
|  |   * IDT ICS932S401 | ||
|  |     Prefix: 'ics932s401' | ||
|  |     Addresses scanned: I2C 0x69 | ||
|  |     Datasheet: Publically available at the IDT website | ||
|  | 
 | ||
|  | Author: Darrick J. Wong | ||
|  | 
 | ||
|  | Description | ||
|  | ----------- | ||
|  | 
 | ||
|  | This driver implements support for the IDT ICS932S401 chip family. | ||
|  | 
 | ||
|  | This chip has 4 clock outputs--a base clock for the CPU (which is likely | ||
|  | multiplied to get the real CPU clock), a system clock, a PCI clock, a USB | ||
|  | clock, and a reference clock.  The driver reports selected and actual | ||
|  | frequency.  If spread spectrum mode is enabled, the driver also reports by what | ||
|  | percent the clock signal is being spread, which should be between 0 and -0.5%. | ||
|  | All frequencies are reported in KHz. | ||
|  | 
 | ||
|  | The ICS932S401 monitors all inputs continuously. The driver will not read | ||
|  | the registers more often than once every other second. | ||
|  | 
 | ||
|  | Special Features | ||
|  | ---------------- | ||
|  | 
 | ||
|  | The clocks could be reprogrammed to increase system speed.  I will not help you | ||
|  | do this, as you risk damaging your system! |
