Hello,

Here is a v2 of adding PCIe support for bcm2712 (RPi5), the fisrt
version can be found at [1].

v2 is based on linux-next plus latest changes in pcie-brcmstb driver
[2]. The changes recently made by Jim leaded to a simplified patchset
for bcm2712 enablement coparing with previous version of this series.

Noticeable changes are:

 - Use of msi-range property in the MIP MSI-X controller and DT which
 make possible to avoid few private DT properties. The other noticeable
 change is moving of msi-pci-addr private property to a second 'reg'
 region. I'll appreciate comments on this.

 - Now the PCIe DT nodes are on separate axi{} simple-bus because adding
 it on soc{} adds too much churn in the node (Florian).

 - Added 'quirks' field in pcie_cfg_data to work around an issue (hw bug?)
 with bridge_reset on bcm2712 SoC.

regards,
~Stan

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade
