Add a device tree binding for its USB protocol part. The internal LDO is not covered by this and can just be modelled as a fixed regulator. Add combo of USB 2.0 and USB 3.0 root hub using peer-hub. Signed-off-by: Anand Moon Reviewed-by: Krzysztof Kozlowski --- v3 - address review coments - Krzysztof dropped dr_mode v2 - fix the compatible string and fix the $id - update the commit message. - update the example for use peer-hub node because it combo of USB 2.0 and USB 3.0 hub. - rename the yaml file from vialab,vl817q7.yaml to vialab,vl817.yaml as q7 suffix is ued for USB 3.1 and q5 suffix is used for USB 2.0. --- .../devicetree/bindings/usb/vialab,vl817.yaml | 71 +++++++++++++++++++ 1 file changed, 71 insertions(+) create mode 100644 Documentation/devicetree/bindings/usb/vialab,vl817.yaml diff --git a/Documentation/devicetree/bindings/usb/vialab,vl817.yaml b/Documentation/devicetree/bindings/usb/vialab,vl817.yaml new file mode 100644 index 000000000000..23a13e1d5c7a --- /dev/null +++ b/Documentation/devicetree/bindings/usb/vialab,vl817.yaml @@ -0,0 +1,71 @@ +# SPDX-License-Identifier: GPL-2.0-only or BSD-2-Clause +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/usb/vialab,vl817.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Via labs VL817 USB 3.1 hub controller + +maintainers: + - Anand Moon + +allOf: + - $ref: usb-device.yaml# + +properties: + compatible: + enum: + - usb2109,2817 + - usb2109,817 + + reg: true + + reset-gpios: + maxItems: 1 + description: + GPIO controlling the RESET# pin. + + vdd-supply: + description: + phandle to the regulator that provides power to the hub. + + peer-hub: + $ref: /schemas/types.yaml#/definitions/phandle + description: + phandle to the peer hub on the controller. + +required: + - compatible + - reg + - reset-gpios + - vdd-supply + - peer-hub + +additionalProperties: false + +examples: + - | + #include + + usb { + #address-cells = <1>; + #size-cells = <0>; + + /* 2.0 hub on port 1 */ + hub_2_0: hub@1 { + compatible = "usb2109,2817"; + reg = <1>; + vdd-supply = <&vcc_5v>; + peer-hub = <&hub_3_0>; + reset-gpios = <&gpio 20 GPIO_ACTIVE_LOW>; + }; + + /* 3.1 hub on port 4 */ + hub_3_0: hub@2 { + compatible = "usb2109,817"; + reg = <2>; + vdd-supply = <&vcc_5v>; + peer-hub = <&hub_2_0>; + reset-gpios = <&gpio 20 GPIO_ACTIVE_LOW>; + }; + };
