Looks like the problem with your mail client is that it's wrapping at exactly 80 characters which is too little - you need to leave space for being quoted.

You can't usefully work with voltages without knowing what the actual voltages are - the only sensible stubs we could provide would return errors but then any driver using the stubs would probably fail to do whatever it was doing. With enable and disable we can sensibly stub things out with an always on regulator.
Sorry, I can not get your point here. Let me describe the problem I met:
- regulator_is_supported_voltage is not exported. when I build clk-reg-cpufreq as kernel module, there's a link error.
This is an oversight, I've just fixed it.
- I saw linux/regulator/consumer.h has some dummy functions if !REGULATOR. I tried to make clk-reg-cpufreq driver work even !REGULATOR. I think that's why the dummy functions are there. If regulator_get return NULL, it'll avoid calling other regulator functions. But regulator_is_supported_voltage and regulator_set_voltage_time don't have such dummy ones. Undefined functions.
I can only repeat what I wrote above explaining why no stubs are provided.
