FYI, patch 1 in this series looks fine. Some comments below though:

Please add the following properties here:

	#address-cells = <1>;
	#size-cells = <0>;

This node name should be "regulator", since nodes are generally named
after the class of object they represent. Since all the nodes will then
have the same name, you'll need to add a unit address ("@nnnn") to the
node name.

Nitpicky, but the labels might be more logical as reg_vdd1 rather than
vdd1_reg, but not a big deal.

So, please replace the line above with:

	reg_vdd1: regulator@0 {
		reg = <0>;

And similarly, that would become:

	reg_vdd2: regulator@1 {
		reg = <1>;

etc.
