He is actually creating two device right now..

- create sti-cpufreq device
  - so that sti-cpufreq driver get probed
    - And fix OPPs here first and then create cpufreq-dt device
      - so that cpufreq-dt driver get probed

:)

I already recommended him that he can replace the first two points by
doing things from module_init() instead. And then create cpufreq-dt
device.
