That would make it more obvious which ones to list in the PCIe controller nodes' phys properties. Something like: p2u_hsio_0: p2u@3e10000 { ... }; ... p2u_nvhs_0: p2u@3eb0000 { ... }; ? Also, make sure to drop the leading 0 from unit-addresses. Recent versions of DTC have checks for that in place and will warn about it in recent Linux builds.
