I did end up sorting the new nodes differently so that they are ordered according to the general rules (sort by unit-address, then alphabetically). That's slightly complicated by the fact that the PCI controllers have registers that seem to be right in the middle of the host1x aperture, so I had to bend the rules a little.

There is an issue with that. PCIe nodes have apertures defined in both 32-bit region and 64-bit region which are mentioned through "ranges" property. Apertures defined in 64-bit region do not fit within "ranges" defined for CBB region which can handle only 32-bit "ranges" of CBB sub-nodes and ends @ 0x40000000. It is because of this reason that I kept PCIe nodes outside of CBB master node. Do you agree with my understanding? If yes, can you please move PCIe nodes out of CBB node?

(Also in platform dts file) Yeah, I noticed this discrepancy while doing the final builds and before pushing things out. I think the problem here is that we restricted the CBB region to #address-cells = <1> where it really should've been 2 cells for the addresses given the size of the addressable region. I've reverted my changes for now, but I think eventually we'll want to adjust CBB to be #address-cells = <2> and maybe even #size-cells = <2> to take into account the PCIe ranges. Another possibility might be that PCI is actually on a different "bus" (i.e. not CBB) in which case it'd be best to model that. But the TRM is not very clear about the bus hierarchy.

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 [v9]: * None Changes since [v8]: * None Changes since [v7]: * Replaced 'core_apb' with 'apb' in reset names * Used macros instead of hardcoded numbers in 'interrupt-map' property * Aligned 'ranges' entries Changes since [v6]: * Removed properties "nvidia,disable-aspm-states" & "nvidia,controller-id". * Modified property "nvidia,bpmp" to include controller-id as well. Changes since [v5]: * Changes 'p2u@xxxxxxxx' to 'phy@xxxxxxxx' * Arranged all PCIe nodes in the order of their addresses Changes since [v4]: * None Changes since [v3]: * None Changes since [v2]: * Included 'hsio' or 'nvhs' in P2U node's label names to reflect which brick they belong to * Removed leading zeros in unit address 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 | 437 +++++++++++++++++++++++ 1 file changed, 437 insertions(+)
