Subject: [PATCH v4 07/18] dt-bindings: usb: dwc3: Add a gpio-usb-connector example
Date: Fri, 7 Feb 2020 01:58:56 +0000 [thread overview]
Message-ID: <20200207015907.242991-8-bryan.odonoghue@linaro.org> (raw)
In-Reply-To: <20200207015907.242991-1-bryan.odonoghue@linaro.org>
A USB connector should be a child node of the USB controller
connector/usb-connector.txt. This patch adds an example of how to do this
to the dwc3 binding descriptions.
It is necessary to declare a connector as a child-node of a USB controller
for role-switching to work, so this example should be helpful to others
implementing that.
