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.

Add P2U (PIPE to UPHY) and PCIe controller nodes to device tree. The Tegra194 SoC contains six PCIe controllers and twenty P2U instances grouped into two different PHY bricks namely High-Speed IO (HSIO-12 P2Us) and NVIDIA High Speed (NVHS-8 P2Us) respectively. Signed-off-by: Vidya Sagar <vidyas@nvidia.com> --- Changes since [v1]: * Flattened all P2U nodes by removing 'hsio-p2u' and 'nvhs-p2u' super nodes * Changed P2U nodes compatible string from 'nvidia,tegra194-phy-p2u' to 'nvidia,tegra194-p2u' * Changed reg-name from 'base' to 'ctl' * Updated all PCIe nodes according to the changes made to DT documentation file arch/arm64/boot/dts/nvidia/tegra194.dtsi | 449 +++++++++++++++++++++++++++++++ 1 file changed, 449 insertions(+)
