[PATCH v3 2/2] ARM: dts: Add the ethernet and ethernet PHY to the cygnus core DT.

From: Eric Anholt
Date: Fri Apr 28 2017 - 18:22:37 EST


Cygnus has a single amac controller connected to the B53 switch with 2
PHYs. On the BCM911360_EP platform, those two PHYs are connected to
the external ethernet jacks.

v2: Call the node "switch", just call the ports "port" (suggestions by
Florian), drop max-speed on the phys (suggestion by Andrew Lunn),
call the other nodes "ethernet" and "ethernet-phy" (suggestions by
Sergei Shtylyov)
v3: Drop another max-speed (Andrew), keep mdio disabled in the shared
dtsi (Florian)
