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";
};
