The 17 compare frame inside can be used for timer purpose. 18 19properties: 20 compatible: 21 const: nxp,sysctr-timer 22 23 reg: 24 maxItems: 1 25 26 interrupts: 27 maxItems: 1 28 29 clocks: 30 maxItems: 1 31 32 clock-names: 33 const: per 34 35required: 36 - compatible 37 - reg 38 - interrupts 39 - clocks 40 - clock-names 41 42additionalProperties: false 43 44examples: 45 - | 46 #include <dt-bindings/interrupt-controller/arm-gic.h> 47 48 timer@306a0000 { 49 compatible = "nxp,sysctr-timer"; 50 reg = <0x306a0000 0x20000>; 51 clocks = <&clk_8m>; 52 clock-names = "per"; 53 interrupts = <GIC_SPI 47 IRQ_TYPE_LEVEL_HIGH>; 54 }; 55
