Isn't there a race between cpufreq-dt and the platform driver to
register first ?

Ah, could you be more specific about the race you're talking of ?

My understanding was that cpufreq-dt-platdev does create the device, and
cpufreq-dt is a driver for it, so there is no race but a direct relationship
AFAIU.

I mean that both the driver may try to register to the cpufreq core if
they are both compiled in a single image.

Euh I still don't follow you. The only driver that can register to the cpufreq
core is cpufreq-dt.

I was wondering on what will happen if both cpufreq-dt and your pxa2xx-cpufreq
driver are present in the same kernel image. In that case the init routines of
both of them will try to call cpufreq_register_driver().

Right.

In my case, cpufreq-dt comes first, and wins.
pxa_cpu_init() calls cpufreq_register_driver() and returns -EEXIST.

Cheers.
