[PATCH] arm64: dts: broadcom: bcm4908: describe internal switch
From: Rafał Miłecki <zajec5@gmail.com>
Date: 2021-01-12 13:19:13
From: Rafał Miłecki <rafal@milecki.pl> 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.
