I'll reply more thoroughly later, but I wanted to address this question.
We're targeting kernel 3.14.x

Is this an answer to question 5?
I think there is some confusion with the "probe" terminology.
I meant "probe" as in "read the current value".
I think you mean "probe" as in "the driver probes for the device through
the probe method."
I meant to ask how often the hwmon framework "polls" the temperature sensor.
Regards.
