The binding doc I have says:

- redistributor-stride : If using padding pages, specifies the stride
  of consecutive redistributors. Must be a multiple of 64kB.

i.e. it doesn't say anything about the size. The _example_ is 2 cells, but
I don't think that is normative.

Unless you can point to a bindings update which specifies strictly two
cells then I think the right answer is the use dt_read_number.

Ian.
