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 };
