1* ARMv7M System Timer 2 3ARMv7-M includes a system timer, known as SysTick. Current driver only 4implements the clocksource feature. 5 6Required properties: 7- compatible : Should be "arm,armv7m-systick" 8- reg : The address range of the timer 9 10Required 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 14Examples: 15 16systick: timer@e000e010 { 17 compatible = "arm,armv7m-systick"; 18 reg = <0xe000e010 0x10>; 19 clocks = <&clk_systick>; 20}; 21 22systick: timer@e000e010 { 23 compatible = "arm,armv7m-systick"; 24 reg = <0xe000e010 0x10>; 25 clock-frequency = <90000000>; 26}; 27
