Hi,
This patchset tries to move all CPUFreq drivers for ARM platforms from arch/arm to drivers/cpufreq directory.
This series is dependent (rebased of) on following patches:
http://www.spinics.net/lists/arm-kernel/msg232540.html https://lkml.org/lkml/2013/3/24/151
I want this series to go through Rafael's tree due to dependencies and so want Ack's by respective maintainers.
These are applied here for people looking to test them:

Normally we keep drivers in alphabetical inside Kconfig and Makefile and over time this was broken for ARM cpufreq drivers. Fix it.

I am unable to apply this patch for testing. Looks like this could be because of:

Can you get rid of that charset="WINDOWS-1252"?

I can't, its MSF exchange server behind this.
And for this reason only i push my patches in my public repo all the time, mentioned in cover-letter.

Too bad. But something needs to be done about it since we all like to apply patches received in email ;). I have seen reports of people configuring gmail to know their @company.com address as another e-mail address they own and then using gmail SMTP to send patches (git config). You should try that.
And for this reason only i push my patches in my public repo all the time, mentioned in cover-letter.
http://git.linaro.org/gitweb?p=people/vireshk/linux.git%3Ba=shortlog%3Bh=ref...
Okay but you never copied me on the cover letter so I only saw this one patch. I will pull your tree and test now.
Thanks, Sekhar

I don't use ARM's email id for sending mails and linaro id uses gmail servers only for sending mails..
The problem is, when i am in office, i can' use google servers to send mails and whatever mail i send from within ARM, they are broken.
I can use linaro servers from outside office without any issues and it is never broken.
And for this reason only i push my patches in my public repo all the time, mentioned in cover-letter.

This series was affecting lots of people and so every patch had a number of people added as cc. I didn't wanted to add everybody in cc of complete patchset.
BUT, i have another idea now. The way i used to add people in cc for specific patches (by editing the patch), i will do the same for cover-letter too next time.
And so all people will receive relevant patches + cover letter.

I pulled your branch and briefly tested it on da850 evm. It doesn't seem to have broken anything. So you can add:

Sure Acked-by: Linus Walleij linus.walleij@linaro.org
This file still #includes a few <mach/*> headers, which stand in the way for multiplatform, but whatever, it will need some heavy patching anyway.
