Subject: [PATCH v2 0/2] Add support for CPM5 controller 1

This patch series introduces support for the second Root Port controller in
the Xilinx Versal Premium CPM5 block. The Versal Premium platform features
two Type-A Root Port controllers operating at Gen5 speed. However, the
error interrupt registers and their corresponding bits are located at
different offsets for Controller 0 and Controller 1.

To handle these differences, the series includes:

A new compatible string for the second Root Port controller in the device
tree bindings.

Driver updates to manage platform-specific interrupt registers and offsets
for both controllers using the new compatible string.

  PCI: xilinx-cpm: Add support for Versal CPM5 Root Port controller 1
