There is one thing you can do to avoid adding OPP entries in the DT.
You can rather add them dynamically with help of: dev_pm_opp_add() and
cpufreq-dt will continue to work with that too.

In what driver should I call these... the clk driver?
(drivers/clk/tegra/cvb.c seems to be doind that)

The problem I run into is that calling get_cpu_device(0) from the
clk driver returns NULL, because topology_init() has not run yet
(to initialize the cpu_sys_devices).

So the OPP table needs to be built *after* topology_init() but
*before* dt_cpufreq_probe().

subsys_initcall(topology_init);
device_initcall(cpufreq_dt_platdev_init);

I'm not sure how to proceed.

Regards.
