No. A phandle is a pointer to an existing node:

        backend = &state_partition;

With state_partition defined somewhere else as:

        mmc0: mmc@0xdeadbeef {
                compatible = "foo-mmc";
                state_partition: partition@10000 {
                        reg = <0x100000 0x20000>;
                };
        };

Or, if you want to use dos partitions, you can go like this:

        backend = &mmc0 "partname:1";
