Subject: [PATCH v3 0/6] Enable IPQ5018 PCI support

From: Sricharan Ramabadhran <quic_srichara@...cinc.com>

This patch series adds the relevant phy and controller
DT configurations for enabling PCI gen2 support
on IPQ5018. IPQ5018 has two phys and two controllers, 
one dual-lane and one single-lane.

Last patch series (v2) submitted dates back to August 27, 2024.
As I've worked to add IPQ5018 platform support in OpenWrt, I'm
continuing the efforts to add Linux kernel support.

v3:
  *) Depends on: https://patchwork.kernel.org/project/linux-arm-msm/cover/20250220094251.230936-1-quic_varada@quicinc.com/
  *) Added 8 MSI SPI and 1 global interrupts (Thanks Mani for confirming)
  *) Added hw revision (internal/synopsys) and nr of lanes in patch 4
     commit msg
  *) Sorted reg addresses and moved PCIe nodes accordingly
  *) Moved to GIC based interrupts
  *) Added rootport node in controller nodes
  *) Tested on Linksys devices (MX5500/SPNMX56)
  *) Link to v2: https://lore.kernel.org/all/20240827045757.1101194-1-quic_srichara@quicinc.com/

v2:
  Fixed all review comments from Krzysztof, Robert Marko,
  Dmitry Baryshkov, Manivannan Sadhasivam, Konrad Dybcio.
  Updated the respective patches for their changes.
