Subject: [PATCH v4 2/4] arm64: dts: imx8mq-nitrogen: add USB HOST support
Date: Tue, 11 May 2021 21:35:59 +0200	[thread overview]
Message-ID: <20210511193601.2584324-3-adrien.grassein@gmail.com> (raw)
In-Reply-To: <20210511193601.2584324-1-adrien.grassein@gmail.com>

Add the description for the USB host port.
This port is linked to a resettable USB HUB so handle
this reset signal with a GPIO hog.
