[PATCH] dt-bindings: PCI: qcom: Allow 'vddpe-3v3-supply' again

[PATCH] dt-bindings: PCI: qcom: Allow 'vddpe-3v3-supply' again

[Johan Hovold]

Commit 756485bfbb85 ("dt-bindings: PCI: qcom,pcie-sc7280: Move SC7280 to
dedicated schema") incorrectly removed 'vddpe-3v3-supply' from the
bindings, which results in DT checker warnings like:

	arch/arm64/boot/dts/qcom/msm8996-sony-xperia-tone-dora.dtb: pcie@600000: Unevaluated properties are not allowed ('vddpe-3v3-supply' was unexpected)
        from schema $id: http://devicetree.org/schemas/pci/qcom,pcie.yaml#

Note that this property has been part of the Qualcomm PCIe bindings
since 2018 and would need to be deprecated rather than simply removed if
there is a desire to replace it with 'vpcie3v3' which is used for some
non-Qualcomm controllers.

Thanks. You could also mention in commit msg that Linux drivers for
msm8996, SM8[123456]50 and few others actually requested that supply. In
any case:

I think Rob Herring suggested [1] adding the property to the root port
node rather than the host. If that suggestion still applies it might be
better to enable the deprecated propertly only for the hosts, which
already used it, and to define a new property at the root port.

You seem to miss the point that this is just restoring status quo (and
that the property has not yet been deprecated).

I assume you've already read my reply to Rob's bot, but here it is for
reference for others:

You are restoring it for all platforms. However in my opinion it's
better to follow Rob's suggestion and to add new property to the
device where it actually belongs, rather than hacking up the PCIe host
device. More importantly with the arrival of the power sequencing
subsystem we can handle powering up PCIe devices properly.

It is already part of the bindings for all platforms.

It is not, it is enabled only for sc7280 and sc8280xp. It has been,
before the mentioned patch. I propopse to enable the property for the
platforms which are using it now (that is +x1e80100, msm8996 and
sdm845), clearly document it as deprecated and start shifting to the
pwrseq and having the power supplies being a part of the root port or
wcn device, depending on the use case.

No, that's both incorrect and irrelevant. It is used by msm8996 and
older platforms by in-kernel DTs as well. But the point is that is has
been part of the bindings an cannot simply be removed as there can be
out-of-tree DTs that are correctly using this property for any of these
platforms.

It can not be removed from the driver, but it definitely can be remove
from bindings.

You apparently ignored the word "simply" in "cannot simply be removed".

Another three weeks have passed and the merge window is now around the
corner.

Can someone please pick this one up for 6.12.

Note that this patch has been acked by the driver maintainer as well as
a DT maintainer.

I applied this to pci/dt-bindings for v6.12.

v6.11 is possible but we'd need a bit of a story to justify it.
756485bfbb85 appeared in v6.9, and the commit log says it fixes a DT
checker warning, which don't make it sound like this is urgent.  Is
there more to it that would make this v6.11 material?

No, merging for 6.12 is fine (e.g. this late in the cycle). Thanks.
