+Nuvoton NPCM7xx SoC EDAC device driver
+
+The Nuvoton NPCM7xx SoC supports DDR4 memory with/without ECC and the driver
+uses the EDAC framework to implement the ECC detection and corrtection.
+
+Required properties:
+- compatible:	should be "nuvoton,npcm7xx-sdram-edac"
+- reg:		Memory controller register set should be <0xf0824000 0x1000>
+- interrupts:	should be MC interrupt #25
+
+Example:
+
+	mc: memory-controller@f0824000 {
+		compatible = "nuvoton,npcm7xx-sdram-edac";
+		reg = <0xf0824000 0x1000>;
+		interrupts = <0 25 4>;
+	};
