it turns out that my patch breaks cpufreq completely...
So it looks as if *I* have a typo :)

Hence I am likely running at constant speed and the
VDD1 regulator is fixed a 1.200V.

root@letux:~# dmesg|fgrep opp
[ 2.426208] cpu cpu0: opp_parse_supplies: Invalid number of elements in opp-microvolt property (6) with supplies (1)
[ 2.438140] cpu cpu0: _of_add_opp_table_v2: Failed to add OPP, -22
root@letux:~# cat /sys/class/regulator/regulator.8/microvolts

The error message looks as if we have to enable multi_regulator.
And that may need to rename cpu0-supply to vdd-supply (unless the
names can be configured).
