Subject: [PATCH v1 2/2] ARM: dts: stm32mp151-prtt1c: add DSA switch and MDIO nodes
Date: Tue, 10 May 2022 14:14:47 +0200	[thread overview]
Message-ID: <20220510121447.216507-2-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20220510121447.216507-1-o.rempel@pengutronix.de>

For netboot support we need to configure switch and PHYs. So, provide
needed nodes.
