+NPCM SoC Random Number Generator
+
+Required properties:
+- compatible  : "nuvoton,npcm750-rng" for the NPCM7XX BMC.
+- reg         : Specifies physical base address and size of the registers.
+
+Optional property:
+- quality : estimated number of bits of true entropy per 1024 bits
+			read from the rng.
+			If this property is not defined, it defaults to 1000.
+
+Example:
+
+rng: rng@f000b000 {
+	compatible = "nuvoton,npcm750-rng";
+	reg = <0xf000b000 0x8>;
+};
