Atmel TRNG (True Random Number Generator) block



Required properties:

- compatible : Should be "atmel,at91sam9g45-trng" or "microchip,sam9x60-trng"

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

- interrupts : the interrupt number for the TRNG block

- clocks: should contain the TRNG clk source



Example:



trng@fffcc000 {

	compatible = "atmel,at91sam9g45-trng";

	reg = <0xfffcc000 0x4000>;

	interrupts = <6 IRQ_TYPE_LEVEL_HIGH 0>;

	clocks = <&trng_clk>;

};
