I think the @d0020000 part needs to be removed for the nodes that
have no reg property.

I think I did not follow the entire discussion. What has led to having
two subnodes in the end, rather than a single node like this?


       interrupt-controller at d0020000 {
              compatible = "marvell,mpic";
              #interrupt-cells = <1>;
              #msi-cells = <1>;
              #address-cells = <1>;
              #size-cells = <1>;
              interrupt-controller;
              msi-controller;
              reg = <0xd0020a00 0x1d0>,
                     <0xd0021070 0x58>;
              marvell,doorbell = <0xd0020a04>;
       };
