4 Subject: [PATCH] arm64: dts: broadcom: bcm4908: describe internal switch
5 MIME-Version: 1.0
6 Content-Type: text/plain; charset=UTF-8
7 Content-Transfer-Encoding: 8bit
8
9 BCM4908 has internal switch with 5 GPHYs. Ports 0 - 3 are always
10 connected to the internal PHYs. Remaining ports depend on device setup.
11
12 Asus GT-AC5300 has an extra switch with its PHYs accessible using the
13 internal MDIO.
14
15 CPU port and Ethernet interface remain to be documented.
