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

Eric Anholt eric at anholt.net
Mon Apr 24 17:50:22 EDT 2017


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.
