Kernel-4.18.0-80.el8_arm,global_timer

• ARM Global Timer
  Cortex-A9 are often associated with a per-core Global timer.

** Timer node required properties:

• compatible : should contain

     * "arm,cortex-a5-global-timer" for Cortex-A5 global timers.
     * "arm,cortex-a9-global-timer" for Cortex-A9 global
         timers or any compatible implementation. Note: driver
         supports versions r2p0 and above.
  

• interrupts : One interrupt to each core

• reg : Specify the base address and the size of the GT timer
  register window.

• clocks : Should be phandle to a clock.

Example:

timer@2c000600 {
    compatible = "arm,cortex-a9-global-timer";
    reg = <0x2c000600 0x20>;
    interrupts = <1 13 0xf01>;
    clocks = <&arm_periph_clk>;
};
