Yes. For rt1711h, the parsing work is done when calling tcpci_register_port and tcpm_register_port. The parsing flow is uploaded by Jun Li after rt1711h is uploaded, so richtek,rt1711h.txt hasn't modified yet. To add rt1711h node and modify the binding doc, richtek,rt1711h.txt, you can refer to Documentation/devicetree/bindings/usb/typec-tcpci.txt >>> +reg = <0x4e>; >>> +status = "ok"; >> >> Can drop this, it is the default. >> > OK. >>> +interrupt-parent = <&gpio27>; >>> +interrupts = <3 IRQ_TYPE_LEVEL_LOW>; >>> +pinctrl-names = "default"; >>> +pinctrl-0 = <&usb_cfg_func>; >>> + >>> +usb_con: connector { >>> +compatible = "usb-c-connector"; >>> +label = "USB-C"; >>> +data-role = "dual"; >>> +power-role = "dual"; >>> +try-power-role = "sink"; >>> +source-pdos = <PDO_FIXED(5000, 500, PDO_FIXED_USB_COMM)>; >>> +sink-pdos = <PDO_FIXED(5000, 500, PDO_FIXED_USB_COMM) >>> +PDO_VAR(5000, 5000, 1000)>; >>> +op-sink-microwatt = <10000000>; >>> +}; >>> + >>> +port { >> >> The connector node should have a 'ports' child with 'port@0' being the >> HS connection. >> > This port and endpoint of the port are used for role_switch matching by fwnode_graph_devcon_match.
