Subject: [PATCH v3 3/3] arm64: dts: nuvoton: npcm845-evb: Add peripheral nodes
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.
