Ok, I have a board which uses this regulator ... can you give me a hint,
how to remove it correctly?

I would do:

move from arch/arm/boot/dts/tps65217.dtsi into board dts

&tps {
+	compatible = "ti,tps65217";
	[...]

and the reg and "regulator-compatible" into the corresponding
nodes ...

                 dcdc1_reg: regulator@0 {
+                        reg = <0>;
+                        regulator-compatible = "dcdc1";

Thanks!

bye,
Heiko
