Subject: [PATCH] arm64: dts: imx8mq-nitrogen: add USB support
Date: Tue, 26 Jan 2021 22:55:11 +0100	[thread overview]
Message-ID: <20210126215511.1056600-1-adrien.grassein@gmail.com> (raw)

add USB support for imx8mq-nitrogen. It consists
in 2 phys: OTG and host.

The OTG port uses a dedicated regulator for vbus.
