You don't really need a node for this. Test against the top level compatible and then find the PMIC nodes by their compatible strings.

+properties:
+ compatible:
+ const: hardkernel,odroid-go-ultra-poweroff
+
+ hardkernel,rk817-pmic:
+ $ref: /schemas/types.yaml#/definitions/phandle
+ description: Phandle to the RK817 PMIC node
+
+ hardkernel,rk818-pmic:
+ $ref: /schemas/types.yaml#/definitions/phandle
+ description: Phandle to the RK818 PMIC node
+
+required:
+ - compatible
+ - hardkernel,rk817-pmic
+ - hardkernel,rk818-pmic
+
+additionalProperties: false

+ poweroff {

+ hardkernel,rk817-pmic = <&rk817>;
