[Letux-kernel] odd things in dt

[Andreas Kemnade]

Hi,

I looked into dt and did a diff with mainline and found several things,
which do not depend on our main battleplace (uart pm) and are different
in upstream and look as it should/need not be different.
Reason was just that I played around with mainline and there used to be
a display with an uncalibrated touchscreen. But I have only white
screen. So I digged around a bit.

hmm, does this cause any difference?

So 0 or 1...

(and several other penirq related stuff)

Also by the same patch.
