Subject: [PATCH v2] arm64: dts: ti: k3-am64* Disable ethernet by default at SoC level
External interfaces should be disabled at the SoC DTSI level, since
the node is incomplete. Disable Ethernet switch and ports in SoC DTSI
and enable them in the board DTS. If the board DTS includes a SoM DTSI
that completes the node description, enable the Ethernet switch and ports
in SoM DTSI.
Reflect this change in SoM DTSIs by removing ethernet port disable.
Signed-off-by: Logan Bristol <logan.bristol@...xas.edu>
---
Changes since v1:
- Enabled cpsw3g and cpsw_port1 in SoM DTSI instead of board DTS
if board DTS included SoM DTSI
