    1 * ARMv7M System Timer
    2 
    3 ARMv7-M includes a system timer, known as SysTick. Current driver only
    4 implements the clocksource feature.
    5 
    6 Required properties:
    7 - compatible      : Should be "arm,armv7m-systick"
    8 - reg             : The address range of the timer
    9 
   10 Required clocking property, have to be one of:
   11 - clocks          : The input clock of the timer
   12 - clock-frequency : The rate in HZ in input of the ARM SysTick
   13 
   14 Examples:
   15 
   16 systick: timer@e000e010 {
   17         compatible = "arm,armv7m-systick";
   18         reg = <0xe000e010 0x10>;
   19         clocks = <&clk_systick>;
   20 };
   21 
   22 systick: timer@e000e010 {
   23         compatible = "arm,armv7m-systick";
   24         reg = <0xe000e010 0x10>;
   25         clock-frequency = <90000000>;
   26 };
