Missing mali regulator in Amlogic dts

I get following error on a  S905W-based system.
lima d00c0000.gpu: dev_pm_opp_set_regulators: no regulator (mali) found: -19

I see mali-supply in the DTS of few other vendors, but in no Amlogic DTS.
Is it missing, or are Amlogic SoCs different here?
In the latter case supposedly drivers/gpu/drm/lima/lima_devfreq.c would
have to be changed to check for the optional regulator and not call
devm_pm_opp_set_regulators() if it's missing.
