Each PIT channel is a +multi-function timer and provide the following usage scenarios: +One 32-bit timer +Two 16-bit timers +Four 8-bit timers +One 16-bit PWM +One 16-bit timer and one 8-bit PWM +Two 8-bit timer and one 8-bit PWM + +Required properties: +- compatible : Should be "andestech,atcpit100" +- reg : Address and length of the register set +- interrupts : Reference to the timer interrupt +- clocks : a clock to provide the tick rate for "andestech,atcpit100" +- clock-names : should be "PCLK" for the external tick timer. + +Examples: + +timer0: timer@f0400000 { + compatible = "andestech,atcpit100"; + reg = <0xf0400000 0x1000>; + interrupts = <2 4>; + clocks = <&clk_pll>; + clock-names = "PCLK"; +};
