Nuvoton NPCM Watchdog
2
-
3
-
Nuvoton NPCM timer module provides five 24-bit timer counters, and a watchdog.
4
-
The watchdog supports a pre-timeout interrupt that fires 10ms before the
5
-
expiry.
6
-
7
-
Required properties:
8
-
- compatible : "nuvoton,npcm750-wdt" for NPCM750 (Poleg), or
9
-
"nuvoton,wpcm450-wdt" for WPCM450 (Hermon), or
10
-
"nuvoton,npcm845-wdt" for NPCM845 (Arbel).
11
-
- reg : Offset and length of the register set for the device.
12
-
- interrupts : Contain the timer interrupt with flags for
13
-
falling edge.
14
-
15
-
Required clocking property, have to be one of:
16
-
- clocks : phandle of timer reference clock.
17
-
- clock-frequency : The frequency in Hz of the clock that drives the NPCM7xx
18
-
timer (usually 25000000).
19
-
20
-
Optional properties:
21
-
- timeout-sec : Contains the watchdog timeout in seconds
22
-
23
-
Example:
24
-
25
-
timer@f000801c {
26
-
compatible = "nuvoton,npcm750-wdt";
27
-
interrupts = <GIC_SPI 47 IRQ_TYPE_LEVEL_HIGH>;
28
-
reg = <0xf000801c 0x4>;
29
-
clocks = <&clk NPCM7XX_CLK_TIMER>;
