It is known not to -affect ZL2004 and ZL6105. The driver automatically sets the interval to 1 ms -except for ZL2004 and ZL6105. To enable 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. +Intersil/Zilker Labs DC-DC controllers require a minimum interval between I2C +bus accesses.
