No. The document I'm converting didn't specify a range. For some of the
hardware supported Marvell doesn't provide documentation, and the
drivers that use this seem to accept any u32 number.

If this needs a range, then I need to make something up. I can do that,
but it will be difficult to defend that number if anyone asks.
