Kernel-4.18.0-80.el8_brcm,bcm2835-aux-uart

• BCM2835 AUXILIAR UART

Required properties:

• compatible: “brcm,bcm2835-aux-uart”
• reg: The base address of the UART register bank.
• interrupts: A single interrupt specifier.
• clocks: Clock driving the hardware; used to figure out the baud rate
  divisor.

Example:

uart1: serial@7e215040 {
    compatible = "brcm,bcm2835-aux-uart";
    reg = <0x7e215040 0x40>;
    interrupts = <1 29>;
    clocks = <&aux BCM2835_AUX_CLOCK_UART>;
};
