Required properties:

- compatible : should be one of

               "fsl,imx21-rnga"

               "fsl,imx31-rnga" (backward compatible with "fsl,imx21-rnga")

               "fsl,imx25-rngb"

               "fsl,imx6sl-rngb" (backward compatible with "fsl,imx25-rngb")

               "fsl,imx6sll-rngb" (backward compatible with "fsl,imx25-rngb")

               "fsl,imx6ull-rngb" (backward compatible with "fsl,imx25-rngb")

               "fsl,imx35-rngc"

- reg : offset and length of the register set of this block

- interrupts : the interrupt number for the RNG block

- clocks : the RNG clk source



Example:



rng@53fb0000 {

	compatible = "fsl,imx25-rngb";

	reg = <0x53fb0000 0x4000>;

	interrupts = <22>;

	clocks = <&trng_clk>;

};
