Hi,

I'm not going to pull this.

I've asked you for about 6 months now (ever since Arnd went on leave)
to please finish his multiplatform work for Exynos. Nothing has happened.

I'm not going to merge any more platform or SoC enablement code
for Samsung platforms until Exynos has been converted over to
multiplatform. Sorry.

Well, it's hard to disagree with you on this. Keeping adding new things
constantly definitely does not make us closer to multiplatform support,
as it only increases codebase of code that needs to be cleaned up and made
multiplatform aware.

However it's not that we're not doing anything towards mutliplatform
support. We're slowly getting there. A bit too slowly, but I'm afraid
this is due to the fact that we have definitely too little manpower
working on mainline support of Samsung SoCs.

As for good news, I already have a series cleaning up PM/sleep support
and making it multiplatform friendly and I'm going to post it tomorrow.
The bad news is that it depends on other series and I'm not sure if we
can get it merged in this release. I'll try to do whatever possible to
merge things as soon as possible, though.

>From smaller things, we still need to sort out Exynos cpufreq driver that
has dependencies on headers in plat-samsung/ and mach-exynos/.
Unfortunately I don't have so much time to work on all the things at the
same time, so I hope that someone else could pick this task up. Marek,
Lukasz, what do you think?

Best regards,
Tomasz

Regarding the cpufreq for Exynos, we do need to clean things up.

It shall be possible to reuse generic cpufreq-cpu0.c and
arm_big_little.c code instead of several copy pasted
exynos[4|5]xxx-cpufreq.c ones.

This change will require some "virtual" clocks implementation for atomic
clocks dividers change.

I've already committed myself to fix this code. When all goes smooth, I
shall deliver some RFC code after new year.

Great!

Sounds like if you can start with this after new year that 3.15 will be
a good target for Exynos multiplatform. It's way overdue, and I would
be very happy to see it completed.

Great!

Sounds like if you can start with this after new year that 3.15 will be
a good target for Exynos multiplatform. It's way overdue, and I would
be very happy to see it completed.

Well, I don't know why this will hurt multiplatform, even you requested that
long time ago. I thought I could finish that by end of this year but it will
be done in Jan. Of course, I'm not sure it could be merged in 3.14, because
it's up to arm-soc tree, it could be sent to before merge window though.

Samsung SoC patches in this pull-request already got review in mailing-list
and it's ready to merge in the mainline. I think, multiplatform support
issue should be handled separately, it's up to you and arm-soc maintainers
though.

And Thomas P Abraham is working on multiplatform for exynos stuff and I
think he could finish in Jan. So I think Samsung folks need to talk
internally to avoid duplication efforts, let me talk to Marek in SRPC.

Well, multiplatform support _has_ been "handled separately" for 6 months
already and as a result not much has happened.

Btw, this isn't personal -- we're not handling Exynos differently from
any other vendor out there. For example, we have made agreements with the
Renesas developers that we will not merge any more non-multiplatform SoC
support from them, and they are now working on migrating theirs over too. But
Exynos is one of the last remaining large platforms that have not yet been
moved over, and it's time to make it a high priority.

Sounds good.

Do you have a list of things that still need resolution, besides cpufreq and
resurrecting Arnd's old patches to move things over?
