'data-size' is already defined in Documentation/devicetree/bindings/eeprom/microchip,93lc46b.yaml. That would be fine, but it's defining bits per word. So I think it's better if we call this something else. 'total-data-size' or 'actual-data-size'? I think Simon had something similar for binman. Rob
