+Freescale RNGC (Random Number Generator Version C)
+
+The driver also supports version B, which is mostly compatible
+to version C.
+
+Required properties:
+- compatible : should be one of
+ "fsl,imx25-rngb"
+ "fsl,imx35-rngc"
+- reg : offset and length of the register set of this block
+- interrupts : the interrupt number for the RNGC block
+- clocks : the RNGC clk source
+
+Example:
+
+rng@53fb0000 {
+ compatible = "fsl,imx25-rngb";
+ reg = <0x53fb0000 0x4000>;
+ interrupts = <22>;
+ clocks = <&trng_clk>;
+};
