There are four PCIe ports on IPQ9574, pcie0 thru pcie3. This series

I believe this makes sense as a monolithic series, as the individual
pieces are not that useful by themselves.
In v2, I've had some issues regarding the dt schema checks. For
transparency, I used the following test invocations to test v3:
make dt_binding_check
DT_SCHEMA_FILES=qcom,pcie.yaml:qcom,ipq8074-qmp-pcie-phy.yaml
make dtbs_check
DT_SCHEMA_FILES=qcom,pcie.yaml:qcom,ipq8074-qmp-pcie-phy.yaml
Alexandru,
Thanks for your contributions to the Qualcomm IPQ chipsets.
I would like to inform you that we have also submitted the patches to
enable the PCIe support on IPQ9574[1][2] and waiting for the ICC
support[3] to land to enable the NOC clocks.

Please take a look at these patches as well.
I think I've seen [1] before -- I thought the series was abandoned.
Since we have the dt-schema and applicability on mainline resolved here,
do you want to use this series as the base for any new PCIe work?
Alex
Thanks,
Kathiravan T.
Changes since v2:
- reworked resets in qcom,pcie.yaml to resolve dt schema errors
- constrained "reg" in qcom,pcie.yaml
- reworked min/max intems in qcom,ipq8074-qmp-pcie-phy.yaml
- dropped msi-parent for pcie node, as it is handled by "msi" IRQ
Changes since v1:
- updated new tables in phy-qcom-qmp-pcie.c to use lowercase hex
numbers
- reorganized qcom,ipq8074-qmp-pcie-phy.yaml to use a single list of
clocks
- reorganized qcom,pcie.yaml to include clocks+resets per compatible
- Renamed "pcie2_qmp_phy" label to "pcie2_phy"
- moved "ranges" property of pcie@20000000 higher up
