| 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: |
