Subject: [PATCH V2 4/5] arm64: dts: imx8mn: Add power-domain reference in USB controller
Date: Sat, 7 Nov 2020 08:00:24 -0600 [thread overview]
Message-ID: <20201107140026.1974312-4-aford173@gmail.com> (raw)
In-Reply-To: <20201107140026.1974312-1-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.
