Changes in v6:
- be more precise about rngc and rngb
- get rid of mxc, rename the file to imx-rngc.txt
- reformat the compatible strings
- use RNGC instead of RNG
- clarify that clock is not optional (remove "should contain")
Changes in v5:
none
Changes in v4:
none
Changes in v3:
- add compatible string for imx35
- remove imx5 from the commit message,
I couldn't find an i.MX SOC that has RNGC
Changes in v2:
none

+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>;
+};
