[PATCH v2 2/2] arm64: dts: renesas: white-hawk-single: Wire-up Ethernet TSN

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On the V4H White-Hawk Single board as oppose to the Quad board the
Ethernet TSN is wired up to a PHY (Marvel 88Q2110/QFN40). Wire up the
connection and enable the TSN0.
