* 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>; | |
}; |
