13 | * bus_speed (unsigned int) | ||
14 | Allows changing of the bus speed. Normally, the bus speed is set by the BIOS | ||
15 | and never needs to be changed. However, some SMBus analyzers are too slow for | ||
16 | monitoring the bus during debug, thus the need for this module parameter. | ||
17 | Specify the bus speed in kHz. | ||

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