Subject: [PATCH 08/10] arm64: dts: zii-ultra: limit USB ports to USB2 speed
Date: Mon, 25 Jan 2021 19:47:34 +0100 [thread overview]
Message-ID: <20210125184736.1226435-8-l.stach@pengutronix.de> (raw)
In-Reply-To: <20210125184736.1226435-1-l.stach@pengutronix.de>
The internal USB is connected to a USB2 hub, the front-panel USB
is wired directly, but does not support USB3 speeds electrically.
Limit both ports accordingly.
