Do you mean to add patternProperties ?

                 nand: nand-controller@43c30000 {
                                 compatible = 
"mxicy,multi-itfc-v009-nand-morph";
                                 reg = <0x43c30000 0x10000>;
                                 clocks = <&clkwizard 0>, <&clkwizard 1>, 
<&clkc 15>;
                                 clock-names = "send", "send_dly", "ps";

+                               nand@0 {
+
+                               };
                 };

something like that.

thanks & best regards,
