This patch enables the use of the generic cpufreq-cpu0 driver on sh73a0.
Providing a regulator, a list of OPPs in DT, combined with a virtual
cpufreq-cpu0 platform device and a clock, attached to it is everything,
the cpufreq-cpu0 driver needs. The first sh73a0 platform, implementing
such CPUFreq support is kzm9g-reference.

With NULL .parent? Shouldn't it be 'platform_bus'?
Look at platform_device_add():
if (!pdev->dev.parent)
pdev->dev.parent = &platform_bus;
Ah, thanks for pointing that out -- I didn't follow the call chain.
I could have passed NULL to platform_device_register_resndata()
too then... Well, now it's too late, and it doesn't matter much anyway.
