"#address-cells" is 3 for pcmcia, so not the default value (which is 2), so you need to put it in. The value of this property is not inherited from the parent node. Absence of a "ranges" property means the child bus is *not* direct mapped into the parent bus space. If the mapping you need is 1-1, put in an empty "ranges" property; if not, you have to put the correct mapping in.
