Subject: [PATCH 1/2] PM / devfreq: Export helper functions for drivers
From: Ørjan Eide
These functions are indended for use by drivers and should be available also
when the driver is built as a module.

There will be some modifications to this patch for consistency with other
pending patches, but please don't worry about them. I'll handle them while
merging this.
Cheers,

Re: [PATCH 0/4] devfreq: exynos: generalize PPMU code
On Sat, Mar 22, 2014 at 2:31 AM, Bartlomiej Zolnierkiewicz b.zolnier...@samsung.com wrote: Hi, This patch series generalizes PPMU support for Exynos devfreq drivers. It is based on top of devfreq: exynos: Fix minor issue and code clean to remove legacy method patch series from Chanwoo Choi (https://lkml.org/lkml/2014/3/19/713). Please note that the patches were only compile tested because Exynos devfreq drivers don't work yet in the upstream kernels (FWIW these changes were briefly tested with the internal tree which has working devfreq drivers). Hi Blartlomiej, Thank you. I'll merge this into devfreq's for-next. Anyway, days ago, I had a short discussion with Chanwoo about providing some common interface for PPMU-like devices (sort of sub device of devfreq device) that provide usage statistics. At this stage, I roughly guess that such a device driver (or whatever entity it is) may be simply a helper for filling out the get_dev_status callback. It is because devfreq's PPMU usage is limited to getting get_dev_status(). As you had done something on PPMU, I guess you may have some idea on this. Cheers, MyungJoo.

Re: [GIT PULL] Samsung Cleanup EXYNOS clock for v3.4
Hi Arnd, Olof, Here is cleanup clock part for EXYNOS SoCs from: git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung.git next/cleanup-exynos-clock Please pull and if any problems, please kindly let me know. Hello, It appears that some patches are missing in this branch; i.e., you seemed not to have pulled one required by this patchset: http://permalink.gmane.org/gmane.linux.kernel.samsung-soc/8474 If the missing patches are included in another branch of yours and being pulled at somewhere else, please never mind. However, it doesn't appear so. Anyway, I'm rebasing the pull-requested branch upon most recent RC, so it'll be available soon (in an hour?) at http://git.infradead.org/users/kmpark/linux-samsung/shortlog/refs/heads/devfreq-for-samsung Cheers! MyungJoo.
