I noticed that the nodes have become a litte disordered after the P2U nodes were added in commit ec142c44b026 ("arm64: tegra: Add P2U and PCIe controller nodes to Tegra234 DT"), so I sorted the SBSA UART node correctly and then reordered the remaining nodes correctly. We should probably have a check for that. I'll see if I can come up with something quickly. Thierry
