[PATCH] dt-bindings: usb: typec-tcpci: convert to DT schema format

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@xxxxxxx>

Convert the binding to DT schema format. The default speed is HS,
so add a dummy port@0 in the example.

Signed-off-by: Peng Fan <peng.fan@xxxxxxx>

V1:
 The default speed is HS, so port@0 is not added for some device tree,
 however the usb-c-connector requires port@0. Not sure we should drop
 the required port@0 from usb-c-connector schema or add a dummy port@0
 for tcpci as what this patch does.

-TCPCI(Typec port cotroller interface) binding
----------------------------------------------
-
-Required properties:
-- compatible:       should be set one of following:
-		    - "nxp,ptn5110" for NXP USB PD TCPC PHY IC ptn5110.
-
-- reg:              the i2c slave address of typec port controller device.
-- interrupt-parent: the phandle to the interrupt controller which provides
-                    the interrupt.
-- interrupts:       interrupt specification for tcpci alert.
-
-Required sub-node:
-- connector: The "usb-c-connector" attached to the tcpci chip, the bindings
-  of connector node are specified in
-  Documentation/devicetree/bindings/connector/usb-connector.yaml
-
-Example:
-
-ptn5110@50 {
-	compatible = "nxp,ptn5110";
-	reg = <0x50>;
-	interrupt-parent = <&gpio3>;
-	interrupts = <3 IRQ_TYPE_LEVEL_LOW>;
-
-	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, 2000, PDO_FIXED_USB_COMM)>;
-		sink-pdos = <PDO_FIXED(5000, 2000, PDO_FIXED_USB_COMM)
-			     PDO_VAR(5000, 12000, 2000)>;
-		op-sink-microwatt = <10000000>;
-
-		ports {
-			#address-cells = <1>;
-			#size-cells = <0>;
-
-			port@1 {
-				reg = <1>;
-				usb_con_ss: endpoint {
-					remote-endpoint = <&usb3_data_ss>;
-				};
-			};
-		};
-	};
-};
