Can you explain this a little further. I'm a bit confused by

Maybe I should remove 'of the registers' to be more clear.

Can you explain this a little further. I'm a bit confused by 'RapidIO address of the registers'. I want to present "This field represents the number of cells [needed to represent the RapidIO address] of the registers." Maybe I should remove 'of the registers' to be more clear. This is completely content-free anyway; the semantics of #address-cells (and #size-cells, which you forgot) are already defined in the base OF spec; what you _should_ be defining here is a) the required value of #address-cells for a rapidio bus; and b) how addresses on that bus are represented (simply as a 64-bit integer, encoded as a pair of 32-bit integers as usual; but it needs to be said).

You should be saying the specifics for your device here; for example, what register blocks of your controller are described in "reg", and in what order?
