1 Kernel driver i2c-ismt 2 3 Supported adapters: 4 * Intel S12xx series SOCs 5 6 Authors: 7 Bill Brown <bill.e.brown@intel.com> 8 9 10 Module Parameters 11 ----------------- 12 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. 18 Available bus frequency settings: 19 0 no change 20 80 kHz 21 100 kHz 22 400 kHz 23 1000 kHz 24 25 26 Description 27 ----------- 28 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 33 something similar to the following: 34 35 00:13.0 System peripheral: Intel Corporation Centerton SMBus 2.0 Controller 0 36 00:13.1 System peripheral: Intel Corporation Centerton SMBus 2.0 Controller 1
