According to the USB 3.2 spec, a SuperSpeed Plus device can operate at
gen2x2, gen2x1, or gen1x2. If the USB controller device supports
multiple lanes at different transfer rates, the user can specify the HW
capability via these new speed strings:
"super-speed-plus-gen2x2"
"super-speed-plus-gen2x1"
"super-speed-plus-gen1x2"
If the argument is simply "super-speed-plus", USB controllers should
default to their maximum transfer rate and number of lanes.

Qualcomm msm8996/sc7180/sdm845 DWC3 compatible DT nodes are supposed to
have a DWC USB3 compatible sub-node to describe a fully functioning USB
interface. Let's use the available DWC USB3 DT schema to validate the
Qualcomm DWC3 sub-nodes.
Note since the generic DWC USB3 DT node is supposed to be named as generic
USB HCD ("^usb(@.*)?") one we have to accordingly fix the sub-nodes name
regexp and fix the DT node example.

DWC USB3 DT node is supposed to be compliant with the Generic xHCI
Controller schema, but with additional vendor-specific properties, the
controller-specific reference clocks and PHYs. So let's convert the
currently available legacy text-based DWC USB3 bindings to the DT schema
and make sure the DWC USB3 nodes are also validated against the
usb-xhci.yaml schema.
Note 1. we have to discard the nodename restriction of being prefixed with
"dwc3@" string, since in accordance with the usb-hcd.yaml schema USB nodes
are supposed to be named as "^usb(@.*)".
Note 2. The clock-related properties are marked as optional to match the
DWC USB3 driver expectation and to improve the bindings mainainability
so in case if there is a glue-node it would the responsible for the
clocks initialization.

Currently the DT bindings of Generic xHCI Controllers are described by
means of the legacy text file. Since such format is deprecated in favor of
the DT schema, let's convert the Generic xHCI Controllers bindings file to
the corresponding yaml files. There will be two of them: a DT schema for
the xHCI controllers on a generic platform and a DT schema validating a
generic xHCI controllers properties. The later will be used to validate
the xHCI controllers, which aside from some vendor-specific features
support the basic xHCI functionality.
An xHCI-compatible DT node shall support the standard USB HCD properties
and custom ones like: usb2-lpm-disable, usb3-lpm-capable,
quirk-broken-port-ped and imod-interval-ns. In addition if a generic xHCI
controller is being validated against the DT schema it is also supposed to
be equipped with mandatory compatible string, single registers range,
single interrupts source, and is supposed to optionally contain up to two
reference clocks for the controller core and CSRs.

Even though the Generic PHY framework is the more preferable way of
setting the USB PHY up, there are still many dts-files and DT bindings
which rely on having the legacy "usb-phy" specified to attach particular
USB PHYs to USB cores. Let's have the "usb-phy" property described in
the generic USB HCD binding file so it would be validated against the
nodes in which it's specified. Mark the property as deprecated to
discourage the developers from using it.

The generic USB properties have been described in the legacy bindings
text file: Documentation/devicetree/bindings/usb/generic.txt . Let's
convert its content into the generic USB, USB HCD and USB DRD DT
schemas. So the Generic USB schema will be applicable to all USB
controllers, USB HCD - for the generic USB Host controllers and the USB
DRD - for the USB Dual-role controllers.
Note the USB DRD schema is supposed to work in conjunction with
the USB peripheral/gadget and USB host controllers DT schemas.

There can be three distinctive types of the USB controllers: USB hosts,
USB peripherals/gadgets and USB OTG, which can switch from one role to
another. In order to have that hierarchy handled in the DT binding files,
we need to collect common properties in a common DT schema and specific
properties in dedicated schemas. Seeing the usb-hcd.yaml DT schema is
dedicated for the USB host controllers only, let's move some common
properties from there into the usb.yaml schema. So the later would be
available to evaluate all currently supported types of the USB
controllers.
While at it add an explicit "additionalProperties: true" into the
usb-hcd.yaml as setting the additionalProperties/unevaluateProperties
properties is going to be get mandatory soon.

Pull ARM device tree updates from Arnd Bergmann:
"Across all platforms, there is a continued move towards DT schema for
validating the dts files. As a result there are bug fixes for mistakes
that are found using these schema, in addition to warnings from the
dtc compiler.
As usual, many changes are for adding support for additional on-chip
and on-board components in the machines we already support.
The newly supported SoCs for this release are:
- MStar Infinity2M, a low-end IP camera chip based on a dual-core
Cortex-A7, otherwise similar to the Infinity chip we already
support. This is also known as the SigmaStar SSD202D, and we add
support for the Honestar ssd201htv2 development kit.
- Nuvoton NPCM730, a Cortex-A9 based Baseboard Management Controller
(BMC), in the same family as the NPCM750. This gets used in the
Ampere Altra based "Fii Kudo" server and the Quanta GSJ, both of
which are added as well.
- Broadcom BCM4908, a 64-bit home router chip based on Broadcom's own
Brahma-B53 CPU. Support is also added for the Asus ROG Rapture
GT-AC5300 high-end WiFi router based on this chip.
- Mediatek MT8192 is a new SoC based on eight Cortex-A76/A55 cores,
meant for faster Chromebooks and tablets. It gets added along with
its reference design.
- Mediatek MT6779 (Helio P90) is a high-end phone chip from last
year's generation, also added along with its reference board. This
one is still based on Cortex-A75/A55.
- Mediatek MT8167 is a version of the already supported MT8516 chip,
both based on Cortex-A35. It gets added along with the "Pumpkin"
single board computer, but is likely to also make its way into
low-end tablets in the future.
For the already supported chips, there are a number of new boards.
Interestingly there are more 32-bit machines added this time than
64-bit. Here is a brief list of the new boards:
- Three new Mikrotik router variants based on Marvell Prestera
98DX3236, a close relative of the more common Armada XP
- A reference board for the Marvell Armada 382
- Three new servers using ASpeed baseboard management controllers,
the actual machines being from Bytedance, Facebook and IBM, and one
machine using the Nuvoton NPCM750 BMC.
- The Galaxy Note 10.1 (P4) tablet, using an Exynos 4412.
- The usual set of 32-bit i.MX industrial/embedded hardware:
* Protonic WD3 (tractor e-cockpit)
* Kamstrup OMNIA Flex Concentrator (smart grid platform)
* Van der Laan LANMCU (food storage)
* Altesco I6P (vehicle inspection stations)
* PHYTEC phyBOARD-Segin/phyCORE-i.MX6UL baseboard
- DH electronics STM32MP157C DHCOM, a PicoITX carrier board for the
aleady supported DHCOM module
- Three new Allwinner SoC based single-board computers:
* NanoPi R1 (H3 based)
* FriendlyArm ZeroPi (H3 based)
* Elimo Initium SBC (S3 based)
- Ouya Game Console based on Nvidia Tegra 3
- Version 5 of the already supported Zynq Z-Turn MYIR Board
- LX2162AQDS, a reference platform for NXP Layerscape LX2162A, which
is a repackaged 16-core LX2160A
- A series of Kontron i.MX8M Mini baseboard/SoM versions
- Espressobin Ultra, a new variant of the popular Armada 3700 based
board,
- IEI Puzzle-M801, a rackmount network appliance based on Marvell
Armada 8040
- Microsoft Lumia 950 XL, a phone
- HDK855 and HDK865 Hardware development kits for Qualcomm sm8250 and
sm8150, respectively
- Three new board variants of the "Trogdor" Chromebook (sc7180)
- New board variants of the Renesas based "Kingfisher" and "HiHope"
reference boards
- Kobol Helios64, an open source NAS appliance based on Rockchips
RK3399
- Engicam PX30.Core, a SoM based on Rockchip PX30, along with a few
carrier boards"
