Same comments as for the other two device trees, plus those below:

These cell-index values for the LEDs look very strange.  How are they
used?

As for serial and gpt, is cell-index really suitable here?

cell-index present for one spi, but not the other makes be even more
suspicious about it's applicability here...

Is lpb another one of these chipselect/offset configurable bus bridge
things?  If so, you should use a 2-cell addressing convention for the
subnodes like fsl localbus and 4xx EBC.

Missing '@'.
