1 Andestech ATCPIT100 timer 2 ------------------------------------------------------------------ 3 ATCPIT100 is a generic IP block from Andes Technology, embedded in 4 Andestech AE3XX, AE250 platforms and other designs. 5 6 This timer is a set of compact multi-function timers, which can be 7 used as pulse width modulators (PWM) as well as simple timers. 8 9 It supports up to 4 PIT channels. Each PIT channel is a 10 multi-function timer and provide the following usage scenarios: 11 One 32-bit timer 12 Two 16-bit timers 13 Four 8-bit timers 14 One 16-bit PWM 15 One 16-bit timer and one 8-bit PWM 16 Two 8-bit timer and one 8-bit PWM 17 18 Required properties: 19 - compatible : Should be "andestech,atcpit100" 20 - reg : Address and length of the register set 21 - interrupts : Reference to the timer interrupt 22 - clock-frequency : The rate in HZ in input of the Andestech ATCPIT100 timer 23 24 Examples: 25 26 timer0: timer@f0400000 { 27 compatible = "andestech,atcpit100"; 28 reg = <0xf0400000 0x1000>; 29 interrupts = <2 4>; 30 clock-frequency = <30000000>; 31 }: 32
