I'm planning to fix OPPs for Exynos4412-Prime and don't wont to duplicate efforts. Also please remember to mention in the cover letter the tree that your patchset is based on (if it is different than the mainline).

But I'm not affiliated with with either Hardkernel nor Samsung, so I have no access to the reference manual and no idea if the frequencies and voltages are actually correct. I don't want to sign off something which I can't verify to be correct... > Also please remember to mention in the cover letter the tree that your > patchset is based on (if it is different than the mainline). I usually base patches on current torvalds/master, but I didn't bother with this series since it's RFC and very much WIP. I don't think even the devfreq bits cleanly apply. Anyway, I'm doing it properly once this is out of RFC.

Both DMC and leftbus adjust regulator voltages (MIF and INT respectively), which have to be in a safe range to allow the BL0 to operate correctly. Signed-off-by: Tobias Jakobi <tjakobi@math.uni-bielefeld.de> --- arch/arm/boot/dts/exynos4412-prime.dtsi | 2 ++ 1 file changed, 2 insertions(+)
