No, this is the wrong way around. The expected operation here is that you apply overlay (1) to the base tree, giving you, say, output1.dtb. output1.dtb is (effectively) a base tree itself, to which you can then apply overlay-(2).
Thanks for the confirmation about this.
Merging overlays is something that could make sense, but fdtoverlay will not do it at present.
FWIW, I think it works fine right now even if it not intentional. I did inspect the output dtb (made by merging two overlays) using fdtdump and it looked okay. But yeah, I understand that we shouldn't do it. -- viresh
