 | Module Parameters | 
 | ----------------- | 
 |  | 
 | * bus_speed (unsigned int) | 
 | Allows changing of the bus speed.  Normally, the bus speed is set by the BIOS | 
 | and never needs to be changed.  However, some SMBus analyzers are too slow for | 
 | monitoring the bus during debug, thus the need for this module parameter. | 
 | Specify the bus speed in kHz. | 
 | Available bus frequency settings: | 
 |   0  no change | 
 |   80 kHz | 
 |   100 kHz | 
 |   400 kHz | 
 |   1000 kHz |

 | Description | 
 | ----------- | 
 |  | 
 | The S12xx series of SOCs have a pair of integrated SMBus 2.0 controllers | 
 | targeted primarily at the microserver and storage markets. | 
 |  | 
 | The S12xx series contain a pair of PCI functions.  An output of lspci will show | 
 | something similar to the following: |
