[PATCH 00/29] dt-bindings: usb: Harmonize xHCI/EHCI/OHCI/DWC3 nodes name

From: Serge Semin
Date: Tue Oct 20 2020 - 08:00:38 EST

As the subject states this series is an attempt to harmonize the xHCI,
EHCI, OHCI and DWC USB3 DT nodes with the DT schema introduced in the
framework of the patchset [1].

Firstly as Krzysztof suggested we've removed a support of DWC USB3
controllers with "synopsys,"-vendor prefix compatible string in favor of
the ones with valid "snps,"-prefix. It's done in the controller driver and
in all the DTS files, which have been unfortunate to define such nodes.

Secondly we suggest to fix the snps,quirk-frame-length-adjustment property
declaration in the Amlogic meson-g12-common.dtsi DTS file, since it has
been erroneously declared as boolean while having uint32 type. Neil said
it was ok to init that property with 0x20 value.

Thirdly the main part of the patchset concern fixing the xHCI, EHCI/OHCI
and DWC USB3 DT nodes name as in accordance with their DT schema the
corresponding node name is suppose to comply with the Generic USB HCD DT
schema, which requires the USB nodes to have the name acceptable by the
regexp: "^usb(@.*)?". Such requirement had been applicable even before we
introduced the new DT schema in [1], but as we can see it hasn't been
strictly implemented for a lot the DTS files. Since DT schema is now
available the automated DTS validation shall make sure that the rule isn't
violated.

Note most of these patches have been a part of the last three patches of
[1]. But since there is no way to have them merged in in a combined
manner, I had to move them to the dedicated series and split them up so to
be accepted by the corresponding subsystem maintainers one-by-one.

Changelog v0:
- As Krzysztof suggested I've created a script which checked whether the
node names had been also updated in all the depended dts files. As a
result I found two more files which should have been also modified:
arch/arc/boot/dts/{axc003.dtsi,axc003_idu.dtsi}
- Correct the USB DWC3 nodes name found in
arch/arm64/boot/dts/apm/{apm-storm.dtsi,apm-shadowcat.dtsi} too.
