+HWRNG support for the timeriomem_rng driver
+
+Required properties:
+- compatible : "timeriomem_rng"
+- reg : base address to sample from
+- period : wait time in microseconds to use between samples
+
+N.B. currently 'reg' must be four bytes wide and aligned
+
+Example:
+
+hwrng@44 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "timeriomem_rng";
+ reg = <0x44 0x04>;
+ period = <1000000>;
+};
