Subject: [PATCH v2 1/1] dt-bindings: extcon: ptn5150: add child node port
Add child node 'port' to allow connect to usb controller to do role-switch.
Add example for id pin of ptn5150 have not connect to main chip's usb id
pin.
Fix below warning:
arch/arm64/boot/dts/freescale/imx8mn-var-som-symphony.dtb: typec@3d: 'port' does not match any of the regexes: 'pinctrl-[0-9]+'
from schema $id: http://devicetree.org/schemas/extcon/extcon-ptn5150.yaml

Change from v1 to v2
- add example for id pin have not connect to main chip's id example.
- commit 095b96b2b fix "port" warning, but add new warning "connector" is
not exist. And follow commit revert this change.
690085d866f08 Revert "arm64: dts: imx8mn-var-som-symphony: Describe the USB-C connector
- I have not board in hand to debug why "connector" is not work.
