Subject: [PATCH V3 4/5] arm64: dts: imx8mn: Add power-domain reference in USB controller
Date: Thu, 29 Apr 2021 16:16:23 -0500 [thread overview]
Message-ID: <20210429211625.1835702-5-aford173@gmail.com> (raw)
In-Reply-To: <20210429211625.1835702-1-aford173@gmail.com>
The USB OTG controller cannot be used until the power-domain is enabled
unless it was started in the bootloader.
Adding the power-domain reference to the OTG node allows the OTG
controller to operate.
