    +* 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>;
    +};
