Probably not related to this particular patch, but does the "reg"
really have to have those extra 0x0s? Why it can't be just:

    reg = <0x14030000 0x1000>;

That comment applies to the whole dts/dtsi. Looks like #address-cells
or #size-cells are bigger than they should be, or I missing something?
