[PATCH v10 4/6] arm64: dts: nuvoton: npcm845: Add peripheral nodes

From: IS20 Tomer Maimon

Date: Sun Oct 04 2026 - 12:13:19 EST


From: Tomer Maimon <tmaimon77@xxxxxxxxx>

Extend the NPCM845 SoC DTSI with the peripheral controller nodes
needed by the evaluation board and downstream platforms. Add the
Ethernet MACs, USB device controllers and PHY, MMC controller, FIU
controllers, memory controller, RNG, ADC, PWM/FAN controller, PSPI,
and I2C buses. Also add the OP-TEE firmware node needed to describe
these blocks.
