A value of 10 is not valid for "mediatek,pull-down-adv" and
"mediatek,pull-up-adv" properties which have defined values of 0-3. It
appears the "10" was written as a binary value. The driver only looks at
the lowest 2 bits, so the value "10" decimal works out the same as if
"2" was used.

This is just a few of the warnings related to mt8183-pinctrl... Mediatek
is #1 for DT warnings on arm64. And by #1, I mean worst. :( It would be
nice to see some progress on fixing them. Otherwise, seeing new Mediatek
bindings rather than fixing the existing stuff makes me grumpy.

Thanks for this fix.
You're absolutely right about this, let me check what I can do (and if I can get
some colleague(s) of mine to look at that while I'm away in August).
