Severe problems with devfreq on linux 5.9.9

There are problems with linux 5.9.9 panfrost driver. It reports strange frequencies and gets stuck either on 200MHz or 800MHz and does not scale.

cat /sys/devices/platform/ff9a0000.gpu/devfreq/ff9a0000.gpu/available_frequencies 3472328296228218214 7094142619989800238 3472328296365385280 499974192 600000000 800000000

The kernel log reports below:

[ 18.139041] devfreq ff9a0000.gpu: Couldn't update frequency transition information.
