[PATCH 0/8] cpufreq: dt: Don't create platform-device from platform code

[PATCH 0/8] cpufreq: dt: Don't create platform-device from platform code

[Viresh Kumar]

Hi,

This migrates rest of the platforms to use cpufreq-dt-platdev.c. There
are few exceptions though:
- mvebu: it uses platform data and its problem will be solved in a
  separate series.
- highbank, s5pv210, sti, tegra124: these platforms already have cpufreq
  drivers in drivers/cpufreq/, which does some other stuff and finally
  create the device. There are sequencing issues, and so they will be
  left as it is.

I have pushed these for testing by:
- kernelci (build/boot testing for ARM)
- Intel's buildbot (build for ARM, build/boot for Intel)

Perhaps that should be done in a separate patch I feel. Will do so after this is

I would do it in the same patch, just like you remove some of the
.init_late() callbacks elsewhere, but it clearly works either way, so
do as you like unless Shawn or Sascha have a strong opinion on the
matter.

This is going to be done once per boot and this shouldn't hurt. And for new
platforms we may do things differently as they are going to use opp-v2 bindings.

And, so I am not really in favor of ifdef hackery :)

I was mainly thinking about kernel size.
If this is done once per boot, the array should be __initconst,
(looking at the code
in next) which is fine as cpufreq_dt_platdev_init() is already __init.

Sure, makes sense.. I will do that as a separate patch.

Though just to correct what I earlier said, if cpufreq-dt is developed as a
module, its done once per module insertion :)
