Kernel-4.18.0-80.el8_brcm,bcm2835

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";

};
