Don't mention the version as this doesn't give the right information.
You tested it over 5.9 + 5.10-rc1 material.

Looks like the stuff from drivers/opp/ti-opp-supply.c supply didn't
work as expected.

One of the major changes came with these patches:

dc279ac6e5b4 cpufreq: dt: Refactor initialization to handle probe deferral properly
dd461cd9183f opp: Allow dev_pm_opp_get_opp_table() to return -EPROBE_DEFER

And that's where I think it may have gone wrong.

Dave: Will you (or someone else from TI) can have a look at it as well
?
