13* bus_speed (unsigned int)
14Allows changing of the bus speed. Normally, the bus speed is set by the BIOS
15and never needs to be changed. However, some SMBus analyzers are too slow for
16monitoring the bus during debug, thus the need for this module parameter.
17Specify the bus speed in kHz.
18Available bus frequency settings:
19 0 no change
20 80 kHz
21 100 kHz
22 400 kHz
23 1000 kHz

29The S12xx series of SOCs have a pair of integrated SMBus 2.0 controllers
30targeted primarily at the microserver and storage markets.
31
32The S12xx series contain a pair of PCI functions. An output of lspci will show
33something similar to the following:
