Subject[PATCH v4] dt-bindings: extcon: usbc-cros-ec: convert extcon-usbc-cros-ec.txt to yaml format
Date
convert the binding file extcon-usbc-cros-ec.txt to
yaml format extcon-usbc-cros-ec.yaml

This was tested and verified on ARM with:
make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/extcon/extcon-usbc-cros-ec.yaml
make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/extcon/extcon-usbc-cros-ec.yaml

Changes since v1:

2 - changing the maintainers
3 - changing the google,usb-port-id property to have minimum 0 and maximum 255

Changes since v2:
1 - Changing the patch subject to start with "dt-bindings: extcon: usbc-cros-ec:"
2 - In the example, adding a parent isp node, a reg field to cros-ec@0
and adding nodes 'extcon0/1' instead of one node 'extcon'.

Changes since v3:
in the example, changing the node isp1 to spi0
