Both of these errors are fixed in the following patches of the series:
[PATCH 17/20] dt-bindings: usb: qcom,dwc3: Validate DWC3 sub-node
[PATCH 15/20] dt-bindings: usb: meson-g12a-usb: Fix FL-adj property value

This patch preserves the original legacy bindings and doesn't touch the
depended bogus DT schemas.

If you already ran 'make dt_binding_check' and didn't see the above

[PATCH 09/20] dt-bindings: usb: Convert DWC USB3 bindings to DT schema

2020-10-14 Thread Serge Semin
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 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(@.*)".

Changelog v2:
- Discard '|' from the descriptions, since we don't need to preserve
  the text formatting in any of them.
- Drop quotes from around the string constants.
- Fix the "clock-names" prop description to be referring the enumerated
  clock-names instead of the ones from the Databook.

-DWC3- USB3 CONTROLLER. Complies to the generic USB binding properties
-  as described in 'usb/generic.txt'
-
-Required properties:
- - compatible: must be "snps,dwc3"
- - reg : Address and length of the register set for the device
- - interrupts: Interrupts used by the dwc3 controller.
- - clock-names: list of clock names. Ideally should be "ref",
-"bus_early", "suspend" but may be less or more.
- - clocks: list of phandle and clock specifier pairs corresponding to
-   entries in the clock-names property.
-
-Exception for clocks:
-  clocks are optional if the parent node (i.e. glue-layer) is compatible to
-  one of the following:

- - usb-phy : array of phandle for the PHY device.  The first element
-   in the array is expected to be a handle to the USB2/HS PHY and
-   the second element is expected to be a handle to the USB3/SS PHY
- - phys: from the *Generic PHY* bindings
- - phy-names: from the *Generic PHY* bindings; supported names are "usb2-phy"
-   or "usb3-phy".
