4 A USB connector node represents a physical USB connector. It should be
5 a child of a USB interface controller.
8 - compatible: describes type of the connector, must be one of:
14 - label: symbolic name for the connector,
15 - type: size of the connector, should be specified in case of USB-A, USB-B
16 non-fullsize connectors: "mini", "micro".
17 - self-powered: Set this property if the usb device that has its own power
20 Optional properties for usb-b-connector:
21 - id-gpios: an input gpio for USB ID pin.
22 - vbus-gpios: an input gpio for USB VBUS pin, used to detect presence of
25 - vbus-supply: a phandle to the regulator for USB VBUS if needed when host
26 mode or dual role mode is supported.
27 Particularly, if use an output GPIO to control a VBUS regulator, should
28 model it as a regulator.
29 see regulator/fixed-regulator.yaml
30 - pinctrl-names : a pinctrl state named "default" is optional
31 - pinctrl-0 : pin control group
32 see pinctrl/pinctrl-bindings.txt
34 Optional properties for usb-c-connector:
35 - power-role: should be one of "source", "sink" or "dual"(DRP) if typec
36 connector has power support.
37 - try-power-role: preferred power role if "dual"(DRP) can support Try.SNK
38 or Try.SRC, should be "sink" for Try.SNK or "source" for Try.SRC.
39 - data-role: should be one of "host", "device", "dual"(DRD) if typec
40 connector supports USB data.
42 Required properties for usb-c-connector with power delivery support:
43 - source-pdos: An array of u32 with each entry providing supported power
44 source data object(PDO), the detailed bit definitions of PDO can be found
45 in "Universal Serial Bus Power Delivery Specification" chapter 6.4.1.2
46 Source_Capabilities Message, the order of each entry(PDO) should follow
47 the PD spec chapter 6.4.1. Required for power source and power dual role.
48 User can specify the source PDO array via PDO_FIXED/BATT/VAR/PPS_APDO()
49 defined in dt-bindings/usb/pd.h.
50 - sink-pdos: An array of u32 with each entry providing supported power
51 sink data object(PDO), the detailed bit definitions of PDO can be found
52 in "Universal Serial Bus Power Delivery Specification" chapter 6.4.1.3
53 Sink Capabilities Message, the order of each entry(PDO) should follow
54 the PD spec chapter 6.4.1. Required for power sink and power dual role.
55 User can specify the sink PDO array via PDO_FIXED/BATT/VAR/PPS_APDO() defined
56 in dt-bindings/usb/pd.h.
57 - op-sink-microwatt: Sink required operating power in microwatt, if source
58 can't offer the power, Capability Mismatch is set. Required for power
59 sink and power dual role.
62 - any data bus to the connector should be modeled using the OF graph bindings
63 specified in bindings/graph.txt, unless the bus is between parent node and
64 the connector. Since single connector can have multiple data buses every bus
65 has assigned OF graph port number as follows:
66 0: High Speed (HS), present in all connectors,
67 1: Super Speed (SS), present in SS capable connectors,
68 2: Sideband use (SBU), present in USB-C.
73 1. Micro-USB connector with HS lines routed via controller (MUIC):
78 compatible = "usb-b-connector";
84 2. USB-C connector attached to CC controller (s2mm005), HS lines routed
85 to companion PMIC (max77865), SS lines to USB3 PHY and SBU to DisplayPort.
86 DisplayPort video lines are routed to the connector via SS mux in USB3 PHY.
91 compatible = "usb-c-connector";
100 usb_con_hs: endpoint {
101 remote-endpoint = <&max77865_usbc_hs>;
106 usb_con_ss: endpoint {
107 remote-endpoint = <&usbdrd_phy_ss>;
112 usb_con_sbu: endpoint {
113 remote-endpoint = <&dp_aux>;
120 3. USB-C connector attached to a typec port controller(ptn5110), which has
121 power delivery support and enables drp.
126 compatible = "usb-c-connector";
129 try-power-role = "sink";
