[GIT PULL] PCI: tegra: Changes for v7.1-rc1

[Thierry Reding]

From: Thierry Reding <thierry.reding@gmail.com>

Hi Lorenzo, Bjorn,

The following changes since commit 6de23f81a5e08be8fbf5e8d7e9febc72a5b5f27f:

  Linux 7.0-rc1 (2026-02-22 13:18:59 -0800)

are available in the Git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux.git tags/tegra-for-7.1-pci

for you to fetch changes up to a0c0906bb09ee2f64690b3b8ffb458b4dbbcb26e:

  PCI: tegra: Add Tegra264 support (2026-03-28 15:00:05 +0100)

This is v3 of the Tegra264 PCI patches that can be found here:

  https://lore.kernel.org/linux-pci/20260326135855.2795149-1-thierry.reding@kernel.org/

This looks ready now, but if there's any more feedback, I will happily
respin these driver patches.

Note that the shortlog and the diffstat below include the dependencies
from the Tegra tree, and that subset will go in through the ARM SoC tree
as well. Effectively what's new in this pull request is just the two PCI
patches, the rest is only included here to resolve the build time
dependencies.

Thanks,
Thierry

PCI: tegra: Changes for v7.1-rc1

This set of patches uses standard wait times for PCIe link monitoring
and build on top of that to add Tegra264 support. It also includes all
the Tegra-specific build-dependencies.

I'm retracting this PR. DT maintainers aren't happy about how I handled
this, so it'll have to wait for another release cycle.

JFYI, We don't pull from PCI patches from other trees. We only merge them by
ourselves.

To clarify this again: the build dependencies are non-trivial and they
can't all go through the PCI tree because there are dependencies with at
least the Tegra tree, hence why a shared branch seemed the best solution
in this case.

But I guess this is all too complicated for everyone involved, so we'll
just try to get in the build dependencies for 7.1 and then defer the PCI
driver until 7.2. That way everyone can follow their standard process.
