Subject: [PATCH v3 06/19] dt-bindings: usb: dwc3: Add a gpio-usb-connector description
Date: Wed, 22 Jan 2020 18:55:57 +0000	[thread overview]
Message-ID: <20200122185610.131930-7-bryan.odonoghue@linaro.org> (raw)
In-Reply-To: <20200122185610.131930-1-bryan.odonoghue@linaro.org>

A USB connector should be a child node of the USB controller
connector/usb-connector.txt. This patch adds a property
"gpio_usb_connector" which declares a connector child device. Code in the
DWC3 driver will then

- Search for "gpio_usb_controller"
- Do an of_platform_populate() if found

This will have the effect of making the declared node a child of the USB
controller and will make sure that USB role-switch events detected with the
gpio_usb_controller driver propagate into the DWC3 controller code
appropriately.
