* 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>; |
|
};
