[PATCH 1/9] arm64: dts: qcom: ipq8074: fix Gen2 PCIe QMP PHY

[Robert Marko]

Serdes register space sizes are incorrect, update them to match the
actual sizes from downstream QCA 5.4 kernel.

[PATCH 2/9] arm64: dts: qcom: ipq8074: fix Gen3 PCIe QMP PHY

[Robert Marko]

IPQ8074 comes in 2 silicon versions:
* v1 with 2x Gen2 PCIe ports and QMP PHY-s
* v2 with 1x Gen3 and 1x Gen2 PCIe ports and QMP PHY-s

v2 is the final and production version that is actually supported by the
kernel, however it looks like PCIe related nodes were added for the v1 SoC.

Now that we have Gen3 QMP PHY support, we can start fixing the PCIe support
by fixing the Gen3 QMP PHY node first.

Change the compatible to the Gen3 QMP PHY, correct the register space start
and size, add the missing misc PCS register space.

v2 is the final and production version that is actually supported by the

Finish the PCIe fixup by using the correct compatible, adding missing ATU
register space, declaring max-link-speed, use correct ranges, add missing
clocks and resets.

[PATCH 9/9] arm64: dts: qcom: ipq8074: correct PCIe QMP PHY output clock names

[Robert Marko]

Current PCIe QMP PHY output name were changed in ("arm64: dts: qcom: Fix
IPQ8074 PCIe PHY nodes") however it did not account for the fact that GCC
driver is relying on the old names to match them as they are being used as
the parent for the gcc_pcie0_pipe_clk and gcc_pcie1_pipe_clk.

This broke parenting as GCC could not find the parent clock, so fix it by
changing to the names that driver is expecting.

Does this imply that the current node doesn't actually work?

If that's the case, could we perhaps adopt Johan Hovolds' new binding
and drop the subnode in favor of just a flat reg covering the whole
QMP region?

Hi Bjorn,
Yes, the node is for a completely different PHY generation, basically
PCIe on IPQ8074
is completely broken, hence this patch series.

I have not seen that so far, any examples?

See
Documentation/devicetree/bindings/phy/qcom,sc8280xp-qmp-pcie-phy.yaml in
v6.2-rc1.

The idea is to, at least, use this for all new platforms introduced.

And if the current definition doesn't actually work I suggest that we
replace it with the new one.

I understand the intention, but these bindings dont match the QMP generation
found in IPQ8074 at all, and Gen3 has already been documented in bindings.

This would require updating the driver to carry the offsets and rework
of bindings to
not require power domains, etc for IPQ8074 as I have not found any
code downstream
to indicate it has GSDC-s for PCIe though I dont have any docs at all
for the SoC.

I was only thinking of the structural difference, not the power-domains
etc. But yes you're right that it means updating the driver and the
binding.

The end result would be much nicer though...

I agree that it would be nicer, though it's asking for many changes, especially
bindings since it's already described there.

The current patchset has been thoroughly tested for months at this point.

How would you like to proceed here, as I would really like to get PCI working
upstream?

If he could do that while rebasing on top of my current pci/qcom branch
that would be ideal, I tried to cherry-pick patches 5,6,7 but 5 does not
apply.

Sure, I will send v2 with that now as after cherry-picking the SM8350 commits
from pci/qcom they all still apply, will fixup the subject capitalization.
