This initial version of the binding only describes USB related aspects of the RTS5411, it does not cover the option of connecting the controller as an i2c slave. Signed-off-by: Matthias Kaehlcke Reviewed-by: Rob Herring --- Changes in v8: - added entry for 'reg' - marked 'companion-hub' as required - changed node name of USB controller to 'usb' Changes in v7: - added type ref for 'companion-hub' property Changes in v6: - Realtek binding instead of generic onboard_usb_hub - added 'companion-hub' property - added reference to 'usb-device.yaml' - 'fixed' indentation of compatible entries to keep yamllint happy - added 'additionalProperties' entry - updated commit message Changes in v5: - updated 'title' - only use standard USB compatible strings - deleted 'usb_hub' node - renamed 'usb_controller' node to 'usb-controller' - removed labels from USB nodes - added 'vdd-supply' to USB nodes Changes in v4: - none Changes in v3: - updated commit message - removed recursive reference to $self - adjusted 'compatible' definition to support multiple entries - changed USB controller phandle to be a node Changes in v2: - removed 'wakeup-source' and 'power-off-in-suspend' properties - consistently use spaces for indentation in example .../bindings/usb/realtek,rts5411.yaml | 62 +++++++++++++++++++ 1 file changed, 62 insertions(+) create mode 100644 Documentation/devicetree/bindings/usb/realtek,rts5411.yaml diff --git a/Documentation/devicetree/bindings/usb/realtek,rts5411.yaml b/Documentation/devicetree/bindings/usb/realtek,rts5411.yaml new file mode 100644 index 000000000000..04ee255eb4f0 --- /dev/null +++ b/Documentation/devicetree/bindings/usb/realtek,rts5411.yaml @@ -0,0 +1,62 @@ +# SPDX-License-Identifier: GPL-2.0-only or BSD-2-Clause +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/usb/realtek,rts5411.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Binding for the Realtek RTS5411 USB 3.0 hub controller + +maintainers: + - Matthias Kaehlcke + +allOf: + - $ref: usb-device.yaml# + +properties: + compatible: + items: + - enum: + - usbbda,5411 + - usbbda,411 + + reg: true + + vdd-supply: + description: + phandle to the regulator that provides power to the hub. + + companion-hub: + $ref: '/schemas/types.yaml#/definitions/phandle' + description: + phandle to the companion hub on the controller. + +required: + - companion-hub + - compatible + - reg + +additionalProperties: false + +examples: + - | + usb { + dr_mode = "host"; + #address-cells = <1>; + #size-cells = <0>; + + /* 2.0 hub on port 1 */ + hub_2_0: hub@1 { + compatible = "usbbda,5411"; + reg = <1>; + vdd-supply = <&pp3300_hub>; + companion-hub = <&hub_3_0>; + }; + + /* 3.0 hub on port 2 */ + hub_3_0: hub@2 { + compatible = "usbbda,411"; + reg = <2>; + vdd-supply = <&pp3300_hub>; + companion-hub = <&hub_2_0>; + }; + };
