This adds the thermal controller and auxadc nodes
to the Mediatek MT2701 dtsi file.

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.
thanks,
