AFAIK, It should work but the we would get a DT warning this, as nvmem does not use of_address based apis to parse this. Which should be totally fixed!! As discussed before once we add support to #address-cells and #size-cells in nvmem core this should not be a problem. --srini Here it is > quiet clear as we have 2 address cells, however even if the number of > cells and the cells size would match it would still be conceptually > wrong as both bindings then use the same address space for something > different.
