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,
Mason
