- Authors:

- 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
