Subject: [v3 PATCH 1/6] dt-bindings: connector: add optional properties for Type-B

Add id-gpios, vbus-gpios, vbus-supply and pinctrl properties for

Signed-off-by: Chunfeng Yun <>
v3 changes:
 1. add GPIO direction, and use fixed-regulator for GPIO controlled
    VBUS regulator suggested by Rob;

v2 changes:
  1. describe more clear for vbus-gpios and vbus-supply suggested by Hans
