Oh, few drivers indeed parse '#dma-xxx' variant. For pl330 schema it was
introduced with 42cf20980cde ("ARM: dts: pl330: Add #dma-cells for
generic dma binding support")
which clearly defines something different than uses in example. I can
imagine that editor added '#' automatically after pressing <enter> when
editing the example.
This wrong variant spread all over and in practice was not detected
because pl330 driver does not parse this field.
I'll fix it.
