* 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>;
};
