From ba67723f946165684fb82f367096ddd126b64d2d Mon Sep 17 00:00:00 2001 From: Fabrice Gasnier Date: Wed, 27 Oct 2021 14:12:32 +0200 Subject: [PATCH] dt-bindings: usb: dwc2: document the port when usb-role-switch is used Document the "port" property, which is used with "usb-role-switch" to describe the bus connector. Definition is inspired from mediatek,mtu3.yaml. This fixes some errors seen when running "make dtbs_check": ... 'port' does not match any of the regexes: 'pinctrl-[0-9]+' From schema: ... Documentation/devicetree/bindings/usb/dwc2.yaml Note: add dependencies so that 'usb-role-switch' without port is valid or both must be present.
