10Module Parameters
11-----------------
12
13* bus_speed (unsigned int)
14Allows changing of the bus speed.  Normally, the bus speed is set by the BIOS
15and never needs to be changed.  However, some SMBus analyzers are too slow for
16monitoring the bus during debug, thus the need for this module parameter.
17Specify the bus speed in kHz.
18Available bus frequency settings:
19  0  no change
20  80 kHz
21  100 kHz
22  400 kHz
23  1000 kHz
