+BCM2835/6368 Random number generator
+
+Required properties:
+
+- compatible : should be one of
+	"brcm,bcm2835-rng"
+	"brcm,bcm-nsp-rng"
+	"brcm,bcm5301x-rng" or
+	"brcm,bcm6368-rng"
+- reg : Specifies base physical address and size of the registers.
+
+Optional properties:
+
+- clocks : phandle to clock-controller plus clock-specifier pair
+- clock-names : "ipsec" as a clock name
+
+Optional properties:
+
+- interrupts: specify the interrupt for the RNG block
+
+Example:
+
+rng {
+	compatible = "brcm,bcm2835-rng";
+	reg = <0x7e104000 0x10>;
+	interrupts = <2 29>;
+};
+
+rng@18033000 {
+	compatible = "brcm,bcm-nsp-rng";
+	reg = <0x18033000 0x14>;
+};
+
+random: rng@10004180 {
+	compatible = "brcm,bcm6368-rng";
+	reg = <0x10004180 0x14>;
+
+	clocks = <&periph_clk 18>;
+	clock-names = "ipsec";
+};
