Kernel-4.18.0-80.el8_arm,armv7m-systick

  • ARMv7M System Timer

ARMv7-M includes a system timer, known as SysTick. Current driver only
implements the clocksource feature.

Required properties:

  • compatible : Should be “arm,armv7m-systick”
  • reg : The address range of the timer

Required clocking property, have to be one of:

  • clocks : The input clock of the timer
  • clock-frequency : The rate in HZ in input of the ARM SysTick

Examples:

systick: timer@e000e010 {
compatible = “arm,armv7m-systick”;
reg = <0xe000e010 0x10>;
clocks = <&clk_systick>;
};

systick: timer@e000e010 {
compatible = “arm,armv7m-systick”;
reg = <0xe000e010 0x10>;
clock-frequency = <90000000>;
};
