[PATCH v5 0/4] PCI: tegra: Add Tegra264 support

[Thierry Reding]

Hi,

this series adds support for the PCIe controllers found on the Tegra264
SoC. There are six instances, one of which is for internal purposes only
and the other five are general purpose.

The first patch tweaks the DT bindings slightly to avoid new DT compiler
warnings that slipped through because they are now disabled by default
(-Wno-unit_address_vs_reg).

Before adding the driver in patch 3, patch 2 introduces some new common
wait times for PCIe and unifies the way that drivers use them. Finally,
patch 4 reorders the reg and reg-names property entries to match the
bindings changes from patch 1.

All of the prerequisites were merged in v7.1-rc1, so this can be applied
to the PCI tree directly. Optionally I can also pick up patch 4 into the
Tegra tree, but there should be no conflicts, so feel free to pick this
up with the rest.

Thanks,
Thierry

Changes in v5:
- address review comments for the PCI driver patch
- Link to v4: https://patch.msgid.link/20260402-tegra264-pcie-v4-0-21e2e19987e8@nvidia.com

Changes in v4:
- strip out dependencies that are going in through the ARM SoC tree
- revert bindings to oneOf construct so that we don't produce new DTC
  warnings
- Link to v3: https://patch.msgid.link/20260326135855.2795149-1-thierry.reding@kernel.org

Changes in v3:
- integrate PCI standard wait times patch into the series to maintain
  bisectability
- fix review comments from Mikko
- Link to v2: https://patch.msgid.link/20260320225443.2571920-1-thierry.reding@kernel.org

Changes in v2:
- fix an issue with sanity-checking disabled BARs
- address review comments
- Link to v1: https://patch.msgid.link/20260319160110.2131954-1-thierry.reding@kernel.org

Thanks,
Thierry
