Some debugfs files, perhaps? :-) In any case, I don't have any problems with this, so I'll let other folks comment.

Personally it isn't that much better than what I did, since each old and new dtbs will for sure differ due to the node names change suggested in this patch. So it will lead to the visual debugging too, which isn't that effective. But your approach is still more demonstrative to make sure that I didn't loose any nodes redefinition, since in the occasion the old and new de-compiled nodes will differ not only by the node names but with an additional old named node. So to speak thanks for suggesting it. I'll try it to validate the proposed changes. Two questions: 1) Any advise of a good inliner/command to compile all dtbs at once? Of course I can get all the updated dtsi'es, then find out all the dts'es which include them, then directly use dtc to compile the found dts'es... On the other hand I can just compile all dts'es, then compare old and new ones. The diff of the non-modified dtb'es will be just empty... 2) What crosc64 is? > > 2. Split it per arm architectures (and proper subject prefix - not > "arch") and subarchitectures so maintainers can pick it up. Why? The changes are simple and can be formatted as a single patch. I've seen tons of patches submitted like that, accepted and then merged. What you suggest is just much more work, which I don't see quite required. > > 3.

Actually it is a fix, because the USB DT nodes should have been named with "usb" prefix in the first place. Legacy DWC USB3 bindings didn't define the nodes naming, but implied to be "usb"-prefixed by the USB HCD schema. The Qualcomm DWC3 schema should have defined the sub-nodes as "dwc3@"-prefixed, which was wrong in the first place. Regarding automatic-pickup-stable-bot if it exists I don't think it scans all the emails, but most likely the stable@vger.kernel.org list only or the emails having the "Fixes:" tag. If I am wrong please give me a link to the bot sources or refer to a doc where I can read about the way it works, to take it into account in future commits. Just to note I submitted patches which did some fixes, had the word "fix" in the subject but weren't selected to be backported to the stable kernel. Anyway I don't really care that much about the subject text using the word "fix" or some else. So if you suggest some better alternative, I'd be glad to consider it. -Sergey > > Best regards, > Krzysztof > > > arch/arm/boot/dts/armada-375.dtsi | 2 +- > > arch/arm/boot/dts/exynos5250.dtsi | 2 +- > > arch/arm/boot/dts/exynos54xx.dtsi | 4 ++-- > > arch/arm/boot/dts/keystone-k2e.dtsi | 4 ++-- > > arch/arm/boot/dts/keystone.dtsi | 2 +- > > arch/arm/boot/dts/ls1021a.dtsi | 2 +- > > arch/arm/boot/dts/omap5-l4.dtsi | 2 +- > > arch/arm/boot/dts/stih407-family.dtsi | 2 +- > > arch/arm64/boot/dts/allwinner/sun50i-h6.dtsi | 2 +- > > arch/arm64/boot/dts/exynos/exynos5433.dtsi | 4 ++-- > > arch/arm64/boot/dts/exynos/exynos7.dtsi | 2 +- > > arch/arm64/boot/dts/freescale/fsl-ls1012a.dtsi | 4 ++-- > > arch/arm64/boot/dts/freescale/fsl-ls1043a.dtsi | 6 +++--- > > arch/arm64/boot/dts/freescale/fsl-ls1088a.dtsi | 4 ++-- > > arch/arm64/boot/dts/freescale/fsl-ls208xa.dtsi | 4 ++-- > > arch/arm64/boot/dts/hisilicon/hi3660.dtsi | 2 +- > > arch/arm64/boot/dts/qcom/apq8096-db820c.dtsi | 4 ++-- > > arch/arm64/boot/dts/qcom/ipq8074.dtsi | 4 ++-- > > arch/arm64/boot/dts/qcom/msm8996.dtsi | 4 ++-- > > arch/arm64/boot/dts/qcom/msm8998.dtsi | 2 +- > > arch/arm64/boot/dts/qcom/qcs404-evb.dtsi | 2 +- > > arch/arm64/boot/dts/qcom/qcs404.dtsi | 4 ++-- > > arch/arm64/boot/dts/qcom/sc7180.dtsi | 2 +- > > arch/arm64/boot/dts/qcom/sdm845.dtsi | 4 ++-- > > arch/arm64/boot/dts/qcom/sm8150.dtsi | 2 +- > > 25 files changed, 38 insertions(+), 38 deletions(-) > >

I seriously doubt anyone is using the APM machines with DT (even ACPI is somewhat doubtful). I say change them. Or remove the dts files and see what happens. Either way it can always be reverted. Rob

But after that the > controller is registered as xhci-hcd device so it's serviced by the xHCI driver, in Dual-role or host-only builds, that's correct. We can also have peripheral-only builds (both SW or HW versions) which means xhci isn't even in the picture.

In that case perhaps we'll need to apply the xHCI DT schema conditionally. Like this: - allOf: - - $ref: usb-xhci.yaml# + allOf: + - if: + properties: + dr_mode: + const: peripheral + then: + $ref: usb-hcd.yaml# + else: + $ref: usb-xhci.yaml# Note, we need to have the peripheral device being compatible with the usb-hcd.yaml schema to support the maximum-speed, dr_mode properties and to comply with the USB node naming constraint. -Sergey > > -- > balbi

It doesn't really matter though, or at least it does for what the new name might be, but the old one currently used is still pretty bad. The DT spec says that the node name is the class of the device. "usb" as the HCD binding mandates is one, but the current nodes currently have completely different names from one DT to another - which is already an issue - and most of them have dwc3 or some variant of it, which doesn't really qualify for a class name.

In accordance with the DWC USB3 bindings the corresponding node name is suppose to comply with Generic USB HCD DT schema, which requires the USB nodes to have the name acceptable by the regexp: "^usb(@.*)?" . But a lot of the DWC USB3-compatible nodes defined in the ARM/ARM64 DTS files have name as "^dwc3@.*" or "^usb[1-3]@.*" or even "^dwusb@.*", which will cause the dtbs_check procedure failure. Let's fix the nodes naming to be compatible with the DWC USB3 DT schema to make dtbs_check happy. Note we don't change the DWC USB3-compatible nodes names of arch/arm64/boot/dts/apm/{apm-storm.dtsi,apm-shadowcat.dtsi} since the in-source comment says that the nodes name need to be preserved as "^dwusb@.*" for some backward compatibility. Signed-off-by: Serge Semin <Sergey.Semin@baikalelectronics.ru> --- Please, test the patch out to make sure it doesn't brake the dependent DTS files.
