Can you point me to the DTS with which you are seeing this issue ?
I am trying to reproduce the issue but so far not successful. I did
move to power-domains for CPUFreq on Juno. IIUC all we need is both cpufreq
and performance genpd drivers in the kernel and then GPU using perf genpd
fails with probe deferral right ? I need pointers to reproduce the issue
so that I can check if what I have cooked up as a solution really works.
