AFAICT, you can have negative numbers in dts files (see [1] and [2]) and
the DT schema certainly supports signed integers, but dt_binding_check
seems to interpret all cells as unsigned 32bit integers because that's
what they are, really. In kernel code this is not a problem because you
can cast the value back to a signed int before you run your own sanity
checks on them.
