From: Thomas Abraham <[e-mail]>

For Exynos4210 platforms, add CPU operating points and CPU
regulator supply properties for migrating from Exynos specific
cpufreq driver to using generic cpufreq driver.

Changes by Bartlomiej:
- removed Exynos5250 and Exynos5420 support for now

Rebased and applied to my tree, I'll sent it later to Kukjin unless he
picks it by himself from LKML.

Hi, as far as I know, this is for v4.2 not v4.1 so it will be applied based on
v4.2-rc1 after v4.2-rc1 release.

Thanks,
Kukjin

You mean it is for v4.3, not v4.2?

Oops, yes v4.3.

Thanks for the correction.

Kukjin & Krzysztof,

I'm confused on this point. I was planning to take patches 1, 2, 3, 5
and 6 towards 4.2 (e.g. in the pull request that I'll send out this
week).

Is patch 4 going out for 4.2 or 4.3?

Regards,
Mike

It is quite late for sending pull request to arm-soc for 4.2.
For example SoCFPGA pull request from last week was rejected:
http://comments.gmane.org/gmane.linux.ports.arm.kernel/417980

If you want to take it for 4.2 then I am fine with it but this will
cause some easy but annoying conflicts. There aren't difficult - just
most of nodes in board DTS changed their place.

Example of resolution (target file after merge, with cpu nodes reordered
alphabetically):

Taking all patches together would be a preferred solution from my POV.

It would also be great if it could happen in v4.2 (all code changes are
practically limited to our Exynos4210 platform so I hope that it should
be fine) as it would be easier to work on Exynos4x12, Exynos5250 and
Exynos542x/5800 patch series.

This patch is needed for v4.2 as other changes has been already
merged.

Krzysztof/Kukjin, could you please take care of it?

Of course! It is already in my queue. I'll send it later to Kukjin for
4.3 (unless he picks it also).

BTW for other patchsets you still need acks from Samsung clock
maintainers. Did you poke Sylwester or Tomasz about it?

It is in your queue for v4.3 but the patch is needed for v4.2,
without it cpufreq support will not work for Exynos4210 platforms.

> maintainers. Did you poke Sylwester or Tomasz about it?

Sylwester, please review/ack Samsung specific clock changes in
Exynos5250 cpufreq and Exynos4x12 cpufreq patch series.

Patch series:

* [PATCH v3 0/4] cpufreq: use generic cpufreq drivers for Exynos5250 platform
  (http://lkml.org/lkml/2015/7/1/311)

* [PATCH v2 0/7] cpufreq: use generic cpufreq drivers for Exynos4x12 platform
  (http://lkml.org/lkml/2015/7/9/419)

Samsung clock specific changes:

* [PATCH v3 1/4] clk: samsung: exynos5250: add cpu clock configuration data
  and instantiate cpu clock
  (http://lkml.org/lkml/2015/7/1/313)

* [PATCH v2 4/7] clk: samsung: exynos4x12: add cpu clock configuration data
  and instantiate cpu clock
  (http://lkml.org/lkml/2015/7/9/424)

Hmm... it makes sense to push it during this rc-cycle to bring back
crippled feature.

BTW corresponding changes for Exynos4210 has already been merged and 2 above
patches are quite obvious so review should be very quick & simple.

[ Unfortunately Sylwester is currently very busy with a more priority work so
  it may still take some time to get his ACKs. ]

The review would be fast and already Javier or me provided such.

Anyway if you want to merge it through different tree it would be
expected to get an ack from bypassed maintainer.

~1 meter for the most of the time :) .

It is much longer distance between you and me now!

Krzysztof
