The base for a patch series is generally the most recent rc1. If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date: pip3 install dtschema --upgrade Please check and re-submit.

The Realtek RTS5411 is a USB 3.0 hub controller with 4 ports. 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 <mka@chromium.org> --- 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 | 58 +++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 Documentation/devicetree/bindings/usb/realtek,rts5411.yaml
