+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>;
+ };
