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 (v3) submitted dates back to August 30, 2024.
As I've worked to add IPQ5018 platform support in OpenWrt, I'm
continuing the efforts to add Linux kernel support.
v4:
*) removed dependency as the following have been applied:
dt-bindings: phy: qcom,uniphy-pcie: Document PCIe uniphy
phy: qcom: Introduce PCIe UNIPHY 28LP driver
dt-bindings: PCI: qcom: Document the IPQ5332 PCIe controller
Link: https://lore.kernel.org/all/20250313080600.1719505-1-quic_varada@xxxxxxxxxxx/
*) added Mani's RB tag to: PCI: qcom: Add support for IPQ5018
*) Removed power-domains property requirement in dt-bindings for IPQ5018
and removed Krzysztof's RB tag from:
dt-bindings: PCI: qcom: Add IPQ5018 SoC
*) fixed author chain and retained Sricharan Ramabadhran in SoB tags and
kept Nitheesh Sekar as the original author
*) Removed comments as per Konrad's comment in:
arm64: dts: qcom: ipq5018: Add PCIe related nodes
*) Link to v3 submitted by Sricharan Ramabadhran:

v3 (incorrectly versioned):
*) Depends on
Link: https://patchwork.kernel.org/project/linux-arm-msm/cover/20250220094251.230936-1-quic_varada@xxxxxxxxxxx/
*) 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:
Link: https://lore.kernel.org/all/20240827045757.1101194-1-quic_srichara@xxxxxxxxxxx/
v3:
Added Reviewed-by tag for patch#1.
Fixed dev_err_probe usage in patch#3.
Added pinctrl/wak pins for pcie1 in patch#6.
v2:
Fixed all review comments from Krzysztof, Robert Marko,
Dmitry Baryshkov, Manivannan Sadhasivam, Konrad Dybcio.
