2
3Nuvoton NPCM timer module provides five 24-bit timer counters, and a watchdog.
4The watchdog supports a pre-timeout interrupt that fires 10ms before the
5expiry.
6
7Required properties:
8- compatible : "nuvoton,npcm750-wdt" for NPCM750 (Poleg).
9- reg : Offset and length of the register set for the device.
10- interrupts : Contain the timer interrupt with flags for
11 falling edge.
12
13Required clocking property, have to be one of:
14- clocks : phandle of timer reference clock.
15- clock-frequency : The frequency in Hz of the clock that drives the NPCM7xx
16 timer (usually 25000000).
17
18Optional properties:
19- timeout-sec : Contains the watchdog timeout in seconds

21Example:
22
23timer@f000801c {
24 compatible = "nuvoton,npcm750-wdt";
25 interrupts = <GIC_SPI 47 IRQ_TYPE_LEVEL_HIGH>;
26 reg = <0xf000801c 0x4>;
27 clocks = <&clk NPCM7XX_CLK_TIMER>;
28};
