  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:
  
    00:13.0 System peripheral: Intel Corporation Centerton SMBus 2.0 Controller 0
    00:13.1 System peripheral: Intel Corporation Centerton SMBus 2.0 Controller 1
