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