The device provides Channel 14 Configuration (CC) logic and 5V VCONN sourcing for ecosystems implementing USB Type-C. The 15 HD3SS3220 can be configured as a Downstream Facing Port (DFP), Upstream Facing Port (UFP) or a 16 Dual Role Port (DRP) making it ideal for any application. 17 18properties: 19 compatible: 20 const: ti,hd3ss3220 21 22 reg: 23 maxItems: 1 24 25 interrupts: 26 maxItems: 1 27 28 ports: 29 $ref: /schemas/graph.yaml#/properties/ports 30 description: OF graph bindings (specified in bindings/graph.txt) that model 31 SS data bus to the SS capable connector. 32 33 properties: 34 port@0: 35 $ref: /schemas/graph.yaml#/properties/port 36 description: Super Speed (SS) MUX inputs connected to SS capable connector. 37 38 port@1: 39 $ref: /schemas/graph.yaml#/properties/port 40 description: Output of 2:1 MUX connected to Super Speed (SS) data bus. 41 42 required: 43 - port@0 44 - port@1 45 46required: 47 - compatible 48 - reg 49 50additionalProperties: false 51 52examples: 53 - | 54 i2c { 55 #address-cells = <1>; 56 #size-cells = <0>; 57 58 hd3ss3220@47 { 59 compatible = "ti,hd3ss3220"; 60 reg = <0x47>; 61 interrupt-parent = <&gpio6>; 62 interrupts = <3>; 63 64 ports { 65 #address-cells = <1>; 66 #size-cells = <0>; 67 port@0 { 68 reg = <0>; 69 hd3ss3220_in_ep: endpoint { 70 remote-endpoint = <&ss_ep>; 71 }; 72 }; 73 port@1 { 74 reg = <1>; 75 hd3ss3220_out_ep: endpoint { 76 remote-endpoint = <&usb3_role_switch>; 77 }; 78 }; 79 }; 80 }; 81 }; 82
