+STMicroelectronics STM32 HW RNG
+===============================
+
+The STM32 hardware random number generator is a simple fixed purpose IP and
+is fully separated from other crypto functions.
+
+Required properties:
+
+- compatible : Should be "st,stm32-rng"
+- reg : Should be register base and length as documented in the datasheet
+- interrupts : The designated IRQ line for the RNG
+- clocks : The clock needed to enable the RNG
+
+Example:
+
+	rng: rng@50060800 {
+		compatible = "st,stm32-rng";
+		reg = <0x50060800 0x400>;
+		interrupts = <80>;
+		clocks = <&rcc 0 38>;
+	};
