My second example was done with the reg property..

                gpio0: gpio at 10100 {
                        compatible = "marvell,orion-gpio";
                        #gpio-cells = <2>;
                        gpio-controller;
                        reg = <0x10100 0x40>;
                }
                chip_cfg at 0 {
                        compatible = "orc,chip_config";
                        // Doubles up on gpio0
                        reg = <0x10100 0x4>;
                };


f1010100-f101013f : /internal at f1000000/gpio at 10100
  f1010100-f1010103 : /internal at f1000000/chip_cfg at 0

What did you try? Maybe order matters?

Regards,
Jason
