Like we discussed I am now trying to implement this but without
success and I am starting to think that it is not that simple unless I
am missing something.

Below tree

gmi@70009000 {
     status = "okay";
     #address-cells = <1>;
     #size-cells = <1>;
     ranges = <4 0x48000000 0x7ffffff>;

     bus@4 {
          compatible = "simple-bus";
          reg = <4 0>;

I don't think you want reg here.

          #address-cells = <1>;
          #size-cells = <1>;

May be ranges here?

         nvidia,snor-mux-mode;
         nvidia,snor-adv-inv;

        can@0 {
              compatible = "nxp,sja1000";
              reg = <0 0x100>;
              ....
     };

     can@40000 {
           compatible = "nxp,sja1000";
           reg = <0x40000 0x100>;
           ....
    };
};
};

Have a look at some other drivers for example:
