[PATCH V2 0/9] cpufreq: dt: Don't create platform-device from platform code

[PATCH V2 0/9] cpufreq: dt: Don't create platform-device from platform code

[Viresh Kumar]

Hi Rafael,

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.

V1->V2:
- Acks from Arnd for all the patches and from few other maintainers
- Finley sent his patch for rockchip 2 minutes before I sent mine :), and so I
  picked his patch instead of mine.
- First patch is new based on suggestions from Geert.
- Arnd suggested to get rid of a init routine in imx patch, that's done as well.

I think we can push this series now that its been Acked by Arnd..

[PATCH V2 1/9] cpufreq: dt: Mark platdev machines array as __initconst

[Viresh Kumar]

The machines array in cpufreq-dt-platdev is used only once at boot time
and so should be marked with __initconst, so that kernel can free up
memory used for it, if required.

[PATCH V2 3/9] cpufreq: imx: Use generic platdev driver

[Viresh Kumar]

The cpufreq-dt-platdev driver supports creation of cpufreq-dt platform
device now, reuse that and remove similar code from platform code.

Note that the complete routine imx27_dt_init() is removed as

of_platform_populate(NULL, of_default_bus_match_table, NULL, NULL);

has same effect as a NULL .init_machine machine callback pointer.
