Re: [PATCH 1/5] CPUFREQ/S3C64xx: Move S3C64xx CPUfreq driver into drivers/cpufreq

Re: [PATCH 1/5] CPUFREQ/S3C64xx: Move S3C64xx CPUfreq driver into drivers/cpufreq

[Kyungmin Park]

Hi Mark,

Instead of samsung tree, it should be handled at cpufreq tree.
CCed the cpufreq maintainer.

Thank you,

Re: [PATCH 1/5] CPUFREQ/S3C64xx: Move S3C64xx CPUfreq driver into drivers/cpufreq

Well, it's a something for both really as both trees are updated.  I
sent the orginal copy of this patch to both places but both sets of
maintainers just ignored it (I've never seen any response from the
cpufreq maintainers on this driver ever since I originally submitted
it).  

At the minute I'm mostly just trying to get some of the backlog of
S3C64xx patches I'm accumilating out of my queue :(

Sorry about that. It's actually in my 'to merge' mailbox, but I've been
laggy at dealing with it recently.  I'll try and clear the backlog in
the next day or two.

thanks,

Ok, I finally got around to sorting this out. It needed some small changes
to fix up rejects in drivers/cpufreq/Makefile, but they looked trivial enough
that I'm sure they're ok. But look them over anyway ?

I also applied the S5PV210/EXYNOS4210 patch which also needed the same fixing.
Both pushed out to cpufreq.next

Let me know if there's anything I've missed

thanks,

	Dave

Hi Mark,

Sorry for late response.
Basically, you're moving is great to me and will review in 1 day.

As I remember, 800Mhz support on S3C6410 is ok and replied about that.
Then isn't there any progress in my side?...I'm outside of my office.

Dave, I'd like to talk about moving Samsung cpufreq drivers. I sent
about Kconfig.arm. If you're ok, will submit remained one to move
all of Samsung cpufreq drivers. And if possible would be better to me,
if someone(you or me) could make some branch to merge into both.

Thanks.

Best regards,
Kgene.

Yes, you replied and said it was OK but it's not appeared in -next yet.

Oops, sorry :(

Maybe I missed.
Ok, will apply in my after checking others.

Then if any updates, let you know.

Thanks.

Kgene.
