We've performed some work on the Generic USB HCD, xHCI and DWC USB3 DT
bindings in the framework of the Baikal-T1 SoC support integration into
the kernel. This patchset is a result of that work.
First of all we moved the generic USB properties from the legacy text
bindings into the USB HCD DT schema. So now the generic USB HCD-compatible
DT nodes are validated taking into account the optional properties like:
maximum-speed, dr_mode, otg-rev, usb-role-switch, etc. We've fixed these
properties a bit so they would correspond to what functionality kernel
currently supports.
Secondly we converted generic USB xHCI text bindings file into the DT
schema. It had to be split up into two bindings: DT schema with generic
xHCI properties and a generic xHCI device DT schema. The later will be
used to validate the pure xHCI-based nodes, while the former can be
utilized by some vendor-specific versions of xHCI.
Thirdly, what was primarily intended to be done for Baikal-T1 SoC USB we
converted the legacy text-based DWC USB3 bindings to DT schema and altered
the result a bit so it would be more coherent with what actually
controller and its driver support. Since we've now got the DWC USB3 DT
schema, we made it used to validate the sub-nodes of the Qualcom, TI and
Amlogic DWC3 DT nodes.
Finally we've also fixed all the OHCI/EHCI, xHCI and DW USB3 compatible DT
nodes so they would comply with the nodes naming scema declared in the USB
HCD DT bindings file.

Changelog v2:
- Thanks to Sergei Shtylyov for suggesting the commit logs grammar fixes:
[PATCH 04/18] dt-bindings: usb: usb-hcd: Add "ulpi/serial/hsic" PHY types
[PATCH 05/18] dt-bindings: usb: usb-hcd: Add "tpl-support" property
[PATCH 11/18] dt-bindings: usb: dwc3: Add interrupt-names property support
[PATCH 13/18] dt-bindings: usb: dwc3: Add Tx De-emphasis restrictions
[PATCH 17/18] dt-bindings: usb: keystone-dwc3: Validate DWC3 sub-node
- Set FL-adj of the amlogiv,meson-g12a-usb controller with value 0x20 instead
of completely removing the property.
- Drop the patch:
[PATCH 02/18] dt-bindings: usb: usb-hcd: Add "wireless" maximum-speed
property value
since "wireless" speed type is depracated due to lack of the device
supporting it.
- Drop quotes from around the compat string constant.
- Discard '|' from the property descriptions, since we don't need to preserve
the text formatting.
- Convert abbreviated form of the "maximum-speed" enum constraint into
the multi-lined version of the list.
- Fix the DW USB3 "clock-names" prop description to be refererring to the
enumerated clock-names instead of the ones from the Databook.
- Add explicit "additionalProperties: true" to the usb-xhci.yaml schema,
since additionalProperties/unevaluatedProperties are going to be mandary
for each binding.
- Use "oneOf: [dwc2.yaml#, snps,dwc3.yaml#]" instead of the bulky "if:
properties: compatibe: ..." statement.
- Discard the "^dwc3@[0-9a-f]+$" nodes from being acceptable as sub-nodes
of the Qualcomm DWC3 DT nodes.
- Add new patches:
[PATCH 18/20] arch: dts: Fix EHCI/OHCI DT nodes name
[PATCH 19/20] arch: dts: Fix xHCI DT nodes name
[PATCH 20/20] arch: dts: Fix DWC USB3 DT nodes name
