Subject: [PATCH] dt-bindings: usb: typec-tcpci: convert to DT schema format
From: Peng Fan <peng.fan@....com>
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@....com>

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>;
