Why did you took my email and pasted it here? http://lists.infradead.org/pipermail/linux-arm-kernel/2015-May/343702.html It is written now in first person so it pretends that you wrote this. You are actually doing this for second time - taking my reply and putting into commit message or changelog. Why? And where is proper changelog?

You put this "Tested-by" since beginning of this patchset (v1) but first it was LDO10. Then you proposed LDO18 and now you use LDO7 from my suggestion. Which of this was tested by Markus because I cannot find his emails with it on LKML?

Markus Reichl tested the earlier version with LDO10.

If you want to quote me, then it's fine. But please indicate that this is a quote. Thanks for resending. Later I'll give the patchset a try on my XU3-Lite.
