Subject: [PATCH] dt-bindings: extcon: linux,extcon-usb-gpio: GPIO must be
 provided

From: David Heidelberg <david@...t.cz>

Without providing either ID or VBUS GPIO the driver is not able to operate.
Original text binding says:
  "Either one of id-gpio or vbus-gpio must be present."

Fixes: 79a31ce03f41 ("dt-bindings: extcon: convert extcon-usb-gpio.txt to yaml format")
