[PATCH 0/2] PCI: dwc: Add multi-port controller support

[Sumit Kumar]

This series adds support for multi-port PCIe controllers in the DesignWare
driver. Currently, the driver only supports a single Root Port with
controller-level properties, which doesn't work for multi-port controllers
where each port may have different configurations.

This series introduces a per-port structure and parsing API that allows 
each Root Port to be configured independently via pcie at N child nodes in
device tree, while maintaining backward compatibility with existing 
single-port bindings.
