Subject: [PATCHv4 2/5] ARM: dts: imx6q-bx50v3: Add internal switch
Date: Tue, 16 Jan 2018 11:19:55 +0100 [thread overview]
Message-ID: <20180116101958.19711-3-sebastian.reichel@collabora.co.uk> (raw)
In-Reply-To: <20180116101958.19711-1-sebastian.reichel@collabora.co.uk>
B850v3, B650v3 and B450v3 all have a GPIO bit banged MDIO bus to
communicate with a Marvell switch. On all devices the switch is
connected to a PCI based network card, which needs to be referenced
by DT, so this also adds the common PCI root node.
