Hmm, does this mean that I should take all these three patches and
hold
the patches in next merge window until the above patch has been
merged?

Yes, this patch is base on auxadc patchset.

Patch 3/3 can not be applied on top of upstream kernel, so I guess it
still has some other dependencies.
I think I can apply patch 1, 2 first. And patch 3/3 should be handled
in the dt tree.

Sorry, this patch is also need Mediatek's clock patchset what I miss to
add in dependency list, I would resend this dt tree once clock patch
merge, or resend this for right dependency on next version, thank you.

Actually, since patch1/patch2 would be OK so far, I would just only
resend patch3 after MTK clock pathcset ready, I prefer to merge
patch1/patch2 if possible, thank you.


From my side that's ok.

Regards,
Matthias
