-* 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>;
-};
