Therefore cpufreq can't be used on this system as of today. Other systems might face similar issues with too optimistic SCPI SVFS clock rates. This RfC patch series addresses this by allowing to define a max frequency per clock via DT. All frequencies for the respective clock exceeding this threshold will be ignored.
