[PATCH v2 2/2] arm64: dts: nuvoton: npcm845-evb: Add peripheral nodes

Tomer Maimon
2025-09-08T13:00:19Z

Enable peripheral support for the Nuvoton NPCM845 Evaluation Board by
adding device nodes for Ethernet controllers, MMC controller, SPI
controllers, USB device controllers, random number generator, ADC,
PWM-FAN controller, I2C controllers, and PECI interface.
Include MDIO nodes for Ethernet PHYs, reserved memory for TIP, and
aliases for device access.
