| * 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>; |
| }; |
