These patches were sent from your integ branch, on top of :
commit 395df5af4c782ad19fb34b9a2009ca240eeb9749 (khilman-amlogic/v5.4/integ)
Merge: 2fcc5666dd45 9557737987bb
Author: Kevin Hilman <khilman@...libre.com>
Date:   Tue Aug 27 15:39:46 2019 -0700

    Merge branch 'v5.4/testing' into tmp/aml-rebuild

Rebuilt and retested, and I get the OPPs just fine :
# cat /sys/bus/cpu/devices/cpu0/cpufreq/scaling_available_frequencies
100000 250000 500000 666666 1000000 1200000 1404000 1500000 1608000 1704000 1800000 1908000
