Wed Sep 9 11:26:05 PDT 2026
Add support for ifm ZynqMP VHIP6 EvalBoard reference design.
The board is populated with four ethernet ports, QSPI NOR,
eMMC, UART and USB host interfaces.

NOTE: Checkpatch complains about ethernet-phy-id2000.a240 being
undocumented, but the TI DP83822I is generic C45 PHY that
is valided by Documentation/devicetree/bindings/net/ethernet-phy.yaml
---
V2: - Rename lm75 node to sensor@
- Use GPIO_ACTIVE_LOW macro
