Anyway the branch is v4.4-next/driver-samsung or tags/samsung-driver...
Or just for-next should be fine I think.

See below:

Since there is no the branch(tags/samsung-clk-exynos5250-4.4) in clk

just take the patch with Stephen's ack...

  cpufreq: s5pv210: remove superfluous CONFIG_PM ifdefs (2015-10-24
04:34:50 +0900)


Samsung driver udpates for v4.4

- add support for exynos SROM controller DT based driver
  (drivers/soc/samsung/exynos-srom.c)
  : Since the exynos SROM registers are used during Suspend to RAM
so the exynos SROM driver handles the S2R and then we can remove
static mapping for SROM registers.
  : Pankaj tested boot and S2R functionality on Peach-Pi chromebook
  : Pavel tested on SMDK5410 board
  : Krzysztof tested on Trats2 (exynos4412) board
- update Maintainer entry accordingly
- remove superfluous CONFIG_PM ifdefs with Viresh's ack

Krzysztof, I sent a pull request lately because of handling of cross-tree but I
don't think so it causes some missing because it was due to cross tree not only
mine. Please don't worry about that I'll handle it.

Anyway thanks for your gentle reminder.

 The cover letter explains that the series is rebased onto Mauro's
 master with Kukjin's branch merged. The latter does contain
 the exynos5433.dtsi. That said, yes, taking patches 1-3 in
 media subsystem and leaving DT patch to someone else is the
 way to go.

Yes right, as Krzysztof commented, the pull-request has been rejected by
arm-soc even I explained it has been tested on smdk5433, because it will
not be compiled without relevant board DT file. And I've rebased when
new -rc1 released until 4.3...because Chanwoo said at that time that
regarding DT file will be submitted but not yet...

To be honest, I'm not sure I can keep the exynos5433 changes for v4.4 in
my tree at this moment...

Could be...hmm...

   Hi Rafael and Viresh,
  
   Since this is a fix to prevent memory leak, it would be better if
   this could be sent to linus during -rc via cpufreq tree.
  
   I'm not planning more pull requests for 4.2 and this one doesn't seem to 
   be
   a good enough reason for a pull request of its own, though.
  
   Of course, if there are more urgent fixes, I can push it along with them,
   but there are none so far.
 
  The cpufreq driver will be removed completely in v4.3 or v4.4 with
  patchset adding cpufreq-dt support for Exynos 4x12. This means that this
  patch makes sense only for 4.2 and as a stable backport (but it was not
  marked as such).
 
 Since I have one more ACPI fix for 4.2, I've applied this one and will
 push it to Linus next week.
 
Rafael, thanks.

Yes, will make a fresh pull request for the exynos cpufreq-dt driver.

 We normally ask that you don't queue up merge requests like these for that
 reason: If there's need to redo an earlier branch there's a lot of work that
 needs to be done on your side. Instead, please wait until previous pull 
 request
 has been merged before you send the next one. Thanks!
 
Yeah, you're right. Actually, it was hard to handle it because of dependencies
of clk and cpufreq...Anyway I'll keep in mind what you suggested.

YES.

 Please try to keep the dependency only driver-dt if you can,

[GIT PULL v2 0/5] Samsung updates for v4.3

[Kukjin Kim]

Hello Arnd, Olof, Kevin

Here is re-spin of pull request for Samsung stuff for v4.3 as per Olof's
suggestion.

Most of this pull-requests are to switch to support generic cpufreq
driver for exynos3250, 4210, 4412 and 5250 and several exynos dt updates.

Note as I commented in each tag, each pull-request(signed tag) has a
dependency with each other, so please keep the ordering in this time.

1) tags/samsung-clk-driver
2) tags/samsung-late-dt
3) tags/samsung-soc
4) tags/samsung-late-cpufreq-driver
5) tags/samsung-defconfig-new

If any problems, please kindly let me know.

Thanks,
Kukjin

[GIT PULL 2nd 3/4] Samsung driver 2nd updates for v4.3

[Kukjin Kim]

Hi,

I've created the signed tag based on previous tags/samsung-driver so you
can see several merge in there. To support cpufreq-dt driver requires
clk/cpufreq/exynos changes together and clk/cpufreq maintainers are
aware of this changes. And we can remove exynos cpufreq driver at last.

Note this drivers update is including previous dependencies and if
you're OK, please pull.

Thanks,
Kukjin

[GIT PULL 2nd 2/4] Samsung DT 3rd updates for v4.3

[Kukjin Kim]

Hi Arnd, Olof, Kevin

This is based on tags/samsung-dt-2 and including exynos4 related clock
changes to support cpufreq-dt driver for exynos4 SoCs. Note that I've
created one more clk topic branch called v4.3-topic/clk-samsung-2 based
on previous one has been merged by Mike into clock tree before but I'm
not sure new one merged into clk tree that's why I've noted its merge in
this signed tag.

Please pull.

Thanks,
Kukjin

 Dear Kukjin,
 
 Can you apply the 2-5 of this series to v4.3? It's getting late but
 maybe they still could go?
 
Once my previous pull-request landed into arm-soc, I'll try to send out this
series 2-5 for v4.3.

Thanks,
Kukjin

 Hi,
 
Hi Bart,

 This patch series removes the use of Exynos4x12 specific support
 from cpufreq-exynos driver and enables the use of cpufreq-dt driver
 for this platform.
 
Thanks for this series.

 This patch series has been tested on Exynos4412 based Odroid-U3 and
 Trats2 boards.
 
Sounds good.

 Depends on:
 - next-20150806 branch of linux-next kernel tree
 - [PATCH V3 00/16] OPP: Add code to support operating-points-v2 bindings
   (http://www.spinics.net/lists/arm-kernel/msg435408.html)
 
BTW, hmm...how can we see this series in v4.3?...to be honest, I don't think it
can be done in v4.3 because of dependencies with PM / OPP series and previous
exynos CPU OPP series in each cross trees...maybe that's why you created based
on linux-next...any idea?

Thanks,
Kukjin

Hi Rafael and Viresh,

Since this is a fix to prevent memory leak, it would be better if
this could be sent to linus during -rc via cpufreq tree.

 Don't you need also cooling-{min,max}-state properties?

 Yes, it is well working without cooling-{min,max}-state or 
 cooling-{min,max}-level.

 I look for the some code to parse cooling-{min,max}-state or 
 cooling-{min,max}-level
 in drivers/thermal/*. But, there are no any code to parse it.

 But, Documentation/devicetree/bindings/thermal/thermal.txt contains just 
 the 'cooling-{min,max}-
 state.

 I think that there are mismatch between document and thermal core driver.

 Thanks for explanation, looks good.

 Dear Kukjin,

 Recent four patchsets (4210 CPU OPP in DTS, cpufreq-dt 5250,
 cpufreq-dt 3250, this patch) are actually an one continuous chain.
 Dependencies are already in mainline. Are you gonna to pick up
 everything?

 Yes, I want and I will. BTW maybe clk change is required together? If so, 
 as you
 know we need to get ack from clk guy. Is my understanding right?

 Right. I think the samsung clock and cpufreq patches still need acks.

 Best regards,
 Krzysztof

 No, I did. I understand that if someone uses opp bindings today with
 some entries as turbo OPPs, cpufreq will use them as normal
 frequencies. And that may harm the board.

 BUT, opp-v2 code isn't ready to be used yet. And platforms should see
 what all is implemented before trying to use them.
 
 OK.
 
 All I was saying is, this isn't a FIX as we haven't introduced the

 Hi all,

 year(s) ago it was discovered that MCT timer and ARM architectured
 timer
 are the same hardware with different interface. Here [1].

 I followed mail-list discussions about removing MCT and using arch
 timer for Exynos5-based SoCs but things aren't moving at least latest
 upstream kernel on odroid-xu3 will use MCT as default timers.
 Maybe the reason are some power-management related things that very
 specific to Samsung. I don't know.


 Idea of this draft patchset comes from Doug patches when he tried to
 optimize read of 64-bit counter located in mmio. [2]
 Why not using cp15 counter instead if possible?

 I hate to burst your bubble here, but...

 ...I think it would be a bad idea to use the cp15 counter on exynos
 5422.  According to Samsung, there are issues where using cp15 could
 sometimes return the wrong value, especially if you happen to read it
 while on an A7 instead of an A15.  It will tend to work pretty well,
 but Samsung claimed that it might not work right on some CPUs or at
 some temperatures.

 I think this is right time when I can say If only I had known about
 it before!.
 
 Yeah, we spent a whole lot of time on this too before giving up after
 we found out it was not possible to use.
 
 
 That's quite interesting especially about temperature issues.
 Maybe it's worth to insert comments in driver/docs about this.
 
 Maybe not a bad idea.  Depends if you think someone else will try to
 do this...  ...and if they do, will they check mailing list traffic.
 
 
 Generally I'd say that if the arch timer works for you: use the arch
 timer.  If the arch timer doesn't work for you, use the MCT.

One more thing, if you change it for your own private platform, it's up
to you but if not, i.e., for mass product, please don't change it.
Because it's not guaranteed even you haven't seen its failure...

 -Doug

 I possess no knowledge if there're any different hw revisions of
 odroid-xu3 on the field
 but looks like arch timer works fine for me on odroid-xu3 Exynos5422
 SoC with upstream kernel.
 
 Well, it looked like it worked for us too.  In fact, I never saw a
 failure.  All I know is that Samsung said: don't do this, it's not a
 good idea.  The performance gain wasn't enough to go against that...
 That's when I started trying to optimize the MCT a little bit.  ;)
 
Yeah and it was tough time for me when I discussed about that with
hardware designer at that time ... haha...

Thanks, Doug.

   Thanks, applied to my tree. I'll send it to Kukjin for v4.3 unless he
   picks it also.
  
   Well, let me see. I'm thinking we need to sort out the cpu ordering and 
   dtsi
   inclusions for exynos5420, 5422 and 5800 related to DT files.
  
   See,
  
   1) exynos5420 DT (cpu0~3: a15, cpu 4~7: a7)
   2) exynos5800 DT is including exynos5420 DT
   3) exynos5422 and exynos5800 based boards are including exynos5800 DT.
  
   Then making exynos5422-cpus DT for exynos5422 based boards?
   (cpu0~3: a7, cpu4~7: a15)
  
   I think, it could cause confusion when new board based on them are added
   because it's not clear and the boot cpu could be selected by bootloader 
   part.
 
  The iROM will check the GPIO pin to select which core is run as cpu0.
  I think no one will change the GPIO pin if a new board which is based
  on exynos5422 :)
 
  Yes, I know the boot sequence and it means it depends on board configuration
  not SoC. That’s why I'm saying it should be handled in board DT file. I 
  think,
  most of current exynos big.LITTLE model should do if it could be changed
  according to board configuration.
 
 I also agreed it's not a SoC configuration since second
 patch(exynos5422.dtsi - exynos5422-cpu.dtsi).
 
 
  
   So how about creating exynos5422-cpus and exynos5420-cpus then including 
   the
   cpus DT file in each board accordingly?
  
   Or more clear way to avoid confusion?
 
  In this situation, all exynos5422 boards(odroid xu3 series and mobile
  phone) have same cpu configurations. If we move the exynos5420 cpu
  configuration from exynos5420.dtsi, we should change all dts which
  including exynos5420.dtsi.
 
  Maybe same board configuration. Just adding inclusion should be fine at this
  moment.
 
  I think we'd better to defer the change until a new exynos5422 board
  which has different cpu configurations is added.
 
  I mean, according to current inclusion of exynos5422 based boards' DT file, 
  it
  is including exynos5420 DT via exynos5800 DT and then override different cpu
  ordering (5422-cpu DT) because of different board configuration (just GPIO
  value) and it is not a good way in this case.
 
 Actually, I don't want to disturb current dts hierarchy even though it
 looks strange. The common features of exynos5800 and exynos5422 should
 be in the exynos5800.dtsi because they shared many things except the
 cpu order.
 Please consider the exynos5422-cpu.dtsi is just board configurations
 to represent cpu order.
 
Yeah, strange and it can cause some confusing...but OK, we don't have much
choice at the moment, so applied to support it even we need some re-work
'current dts hierarchy' next time.

Thanks,
Kukjin

Yeah, actually I couldn't use git send-email when I submitted but just used
e-mail. It should be fine in my local branch.

 2. Could you answer in commit message: Why? Why are you moving the headers?
 
OK, basically we don't need to keep headers in mach/xxx and plat/xxx if it
is not required. For example, actually common.h files in mach-/ have been
made/moved because of the reason before. Someday we did because it was required
to support multi_v7 as well. Anyway it is still required and note that I have
some more patches to move headers which are used only for under drivers/ not
arch side into drivers/. And next step is removing some definitions which are
not used more.

   I noticed that the version that landed in 4.2-rc1 as commit
   f3caa529c6f5 (ARM: multi_v7_defconfig: Enable max77802 regulator, rtc
   and clock drivers) doesn't include this symbol. I guess it was caused
   by a wrong resolved conflict? I'll post a patch to enable the
   regulator again.
 
  As you can see in mentioned mainline commit Kukjin removed it manually:
  [kg...@kernel.org: removing useless REGULATOR_MAX77802 config]
 
  I wonder why?
 
  Seems odd. exynos_defconfig still enables it.
 
It has been removed when I did 'make savedefconfig' at that time maybe because
of dependency with other configs...

  Yeah since it is needed for at least the Exynos5420 Peach Pit and
  Exynos5800 Peach Pi Chromebooks that use this PMIC.
 
  Javier or Krzysztof, please send an incremental fix to enable and I'll pick
  it up as a fix.
 
 
  I already posted an incremental patch [0] and Krzysztof is pushing it
  through Kukjin for 4.3 [1].
 
Yes. I'll send it out to arm-soc in this weekend.

  I guess that's OK and there is no need to add it as a fix for the 4.2
  -rc cycle since this is not really a regression. I mean, the max77802
  regulator driver was never enabled for multi_v7_defconfig before.
 
 Yeah, I came across those emails a little further down. :-) It's all
 good, we'll see it come in later.
 
Thanks,
Kukjin
