+STMicroelectronics HW Random Number Generator
+----------------------------------------------
+
+Required parameters:
+compatible      : Should be "st,rng"
+reg             : Base address and size of IP's register map.
+clocks          : Phandle to device's clock (See: ../clocks/clock-bindings.txt)
+
+Example:
+
+rng@0xfee80000 {
+        compatible      = "st,rng";
+        reg             = <0xfee80000 0x1000>;
+        clocks          = <&clk_sysin>;
+}
