To have the correct semantics this should be:
		reg = <0x3d>, <0x2d>, <0x4d>, <0x5d>;

It is a set of 4 single cell addresses. The other thing is a single 4 cell
address. It will get compiled to the same bytes, but the DT tools should
complain about it, because it doesn't match #address-cells.

Same here.
