BCM2835/6368 Random number generator



Required properties:



- compatible : should be one of

	"brcm,bcm2835-rng"

	"brcm,bcm-nsp-rng"

	"brcm,bcm5301x-rng" or

	"brcm,bcm6368-rng"

- reg : Specifies base physical address and size of the registers.



Optional properties:



- clocks : phandle to clock-controller plus clock-specifier pair

- clock-names : "ipsec" as a clock name



Optional properties:



- interrupts: specify the interrupt for the RNG block



Example:



rng {

	compatible = "brcm,bcm2835-rng";

	reg = <0x7e104000 0x10>;

	interrupts = <2 29>;

};



rng@18033000 {

	compatible = "brcm,bcm-nsp-rng";

	reg = <0x18033000 0x14>;

};



random: rng@10004180 {

	compatible = "brcm,bcm6368-rng";

	reg = <0x10004180 0x14>;



	clocks = <&periph_clk 18>;

	clock-names = "ipsec";

};
