-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>;
