clock-names and even that names - you are right it is not correct and
should be fixed.
Missing 0x0 in reg doesn't matter because it depends on address/size cells.

Real example is the best normally just c&p from existing dts is the way
to go.
But in connection to clocks it doesn't matter what exactly should be
there and I don't think there is any consistency in that. Hopefully this
will be removed by yaml conversion.
