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 1200000 root@letux:~# 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). BR, Nikolaus
