Hello,

This series adds support to the pci-j721e PCIe controller for up to 4x Lane
configuration supported by TI's J784S4 SoC. Bindings are also added for
the num-lanes property which shall be used by the driver. The compatible
for J784S4 SoC is added.

This series is based on linux-next tagged next-20231128.

Regards,
Siddharth.
