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

Yes.
I do not care too much. But it puts the driver on an interesting
position, that is it can work without a regulator driver backing the
cpu voltage but it

There's still a bug that, after rmmod module, cpu0 still has cpufreq
sysfs entry.
cpufreq_unregister_driver can not clean up everything.
unfortunately, I don't have much time to debug cpufreq core.
Log:
root@ubuntu:~# insmod /clk-reg-cpufreq.ko
clk_reg_cpufreq: regulator cpu get failed.

The driver get cpu operation point table from device tree cpu0 node,
and adjusts operating points using clk and regulator APIs.
It support single core and multi-core ARM SoCs. But currently it assume
all cores share the same frequency and voltage.

Have you tried to pass this param from kernel cmdline? What's the

Thanks. I was mistaken on the module name.

Is there any reason you didn't export symbol regulator_is_supported_voltage?
and also it don't have
