Hello,

This series fixes the bindings for:
Documentation/devicetree/bindings/pci/ti,j721e-pci-ep.yaml
Documentation/devicetree/bindings/pci/ti,j721e-pci-host.yaml
by updating the checks added for validating and enforcing the
"num-lanes" property for different compatibles. In the commits
which introduced and extended the checks for the "num-lanes"
property, the property was not truly validated but only described.
Therefore, the bindings are being updated to actually validate
the "num-lanes" property. While at it, checks for "max-link-speed"
are also being introduced. The intent of the aforementioned changes
is to update the bindings for a new SoC namely TI's J722S SoC which
has a similar PCIe controller to TI's AM64 SoC, but differs from it
in terms of its support for Gen3 link speeds. For this reason, a new
compatible is being added instead of reusing the one available for
AM64 SoC.

Series is based on linux-next tagged next-20240117.

Regards,
Siddharth.
