I am fine with adding floating supply similar to below and connect all 
non-connected supply pins to this.

                 floating: regulator@1 {
                         compatible = "regulator-fixed";
                         reg = <1>;
                         regulator-name = "floating";
                 };

If this is fine then I will respin the patch to remove condition.
