14-----------------
15
16* bus_speed (unsigned int)
17
18Allows changing of the bus speed.  Normally, the bus speed is set by the BIOS
19and never needs to be changed.  However, some SMBus analyzers are too slow for
20monitoring the bus during debug, thus the need for this module parameter.
21Specify the bus speed in kHz.
