+Freescale RNGC (Random Number Generator Version C)
+
+Required properties:
+- compatible : Should be "fsl,imx25-rng" or "fsl,imx35-rng"
+- reg : Offset and length of the register set of this block
+- interrupts : the interrupt number for the RNG block
+- clocks: should contain the RNG clk source
+
+Example:
+
+rng@53fb0000 {
+ compatible = "fsl,imx25-rng";
+ reg = <0x53fb0000 0x4000>;
+ interrupts = <22>;
+ clocks = <&trng_clk>;
