From: Rafał Miłecki <rafal@xxxxxxxxxx> USB bindings already allow specifying USB device hard wired to a specific controller port but they don't allow describing port on its own. This fixes: arch/arm/boot/dts/bcm4708-buffalo-wzr-1750dhp.dt.yaml: usb@23000: port@1: 'compatible' is a required property From schema: Documentation/devicetree/bindings/usb/generic-xhci.yaml Signed-off-by: Rafał Miłecki <rafal@xxxxxxxxxx> --- Please check if I got the $nodename part right. Somehow I don't see any errors / warnings when using: something@1 { reg = <1>; }; --- .../devicetree/bindings/usb/usb-hcd.yaml | 4 +- .../devicetree/bindings/usb/usb-port.yaml | 39 +++++++++++++++++++ 2 files changed, 42 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/usb/usb-port.yaml diff --git a/Documentation/devicetree/bindings/usb/usb-hcd.yaml b/Documentation/devicetree/bindings/usb/usb-hcd.yaml index 56853c17af66..b0c6a79cad57 100644 --- a/Documentation/devicetree/bindings/usb/usb-hcd.yaml +++ b/Documentation/devicetree/bindings/usb/usb-hcd.yaml @@ -33,7 +33,9 @@ patternProperties: "^.*@[0-9a-f]{1,2}$": description: The hard wired USB devices type: object - $ref: /usb/usb-device.yaml + oneOf: + - $ref: /usb/usb-port.yaml + - $ref: /usb/usb-device.yaml additionalProperties: true diff --git a/Documentation/devicetree/bindings/usb/usb-port.yaml b/Documentation/devicetree/bindings/usb/usb-port.yaml new file mode 100644 index 000000000000..68fe16c8703e --- /dev/null +++ b/Documentation/devicetree/bindings/usb/usb-port.yaml @@ -0,0 +1,39 @@ +# SPDX-License-Identifier: GPL-2.0-only OR BSD-2-Clause +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/usb/usb-port.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: USB port on USB controller + +maintainers: + - Rafał Miłecki <rafal@xxxxxxxxxx> + +description: | + This binding describes a single USB controller port that doesn't have any + device hard wired. + +properties: + $nodename: + pattern: "^port@[0-9a-f]{1,2}$" + + reg: + description: number of USB controller port + maxItems: 1 + +required: + - reg + +additionalProperties: true + +examples: + - | + usb@11270000 { + reg = <0x11270000 0x1000>; + #address-cells = <1>; + #size-cells = <0>; + + port@1 { + reg = <1>; + }; + }; -- 2.26.2
