Intersil/Zilker Labs DC-DC controllers require a minimum interval between I2C
|

bus accesses. According to Intersil, the minimum interval is 2 ms, though 1 ms
|

appears to be sufficient and has not caused any problems in testing. The problem
|

is known to affect all currently supported chips. For manual override, the
|

driver provides a writeable module parameter, 'delay', which can be used to set
|
||||
the interval to a value between 0 and 65,535 microseconds.
