1Andestech ATCPIT100 timer 2------------------------------------------------------------------ 3ATCPIT100 is a generic IP block from Andes Technology, embedded in 4Andestech AE3XX platforms and other designs. 5 6This timer is a set of compact multi-function timers, which can be 7used as pulse width modulators (PWM) as well as simple timers. 8 9It supports up to 4 PIT channels. Each PIT channel is a 10multi-function timer and provide the following usage scenarios: 11One 32-bit timer 12Two 16-bit timers 13Four 8-bit timers 14One 16-bit PWM 15One 16-bit timer and one 8-bit PWM 16Two 8-bit timer and one 8-bit PWM 17 18Required properties: 19- compatible : Should be "andestech,atcpit100" 20- reg : Address and length of the register set 21- interrupts : Reference to the timer interrupt 22- clocks : a clock to provide the tick rate for "andestech,atcpit100" 23- clock-names : should be "PCLK" for the peripheral clock source. 24 25Examples: 26 27timer0: timer@f0400000 { 28 compatible = "andestech,atcpit100"; 29 reg = <0xf0400000 0x1000>; 30 interrupts = <2>; 31 clocks = <&apb>; 32 clock-names = "PCLK"; 33}; 34
