Nuvoton NPCM Watchdog Nuvoton NPCM timer module provides five 24-bit timer counters, and a watchdog. The watchdog supports a pre-timeout interrupt that fires 10ms before the expiry. Required properties: - compatible : "nuvoton,npcm750-wdt" for NPCM750 (Poleg). - reg : Offset and length of the register set for the device. - interrupts : Contain the timer interrupt with flags for falling edge. Required clocking property, have to be one of: - clocks : phandle of timer reference clock. - clock-frequency : The frequency in Hz of the clock that drives the NPCM7xx timer (usually 25000000). Optional properties: - timeout-sec : Contains the watchdog timeout in seconds Example: timer@f000801c { compatible = "nuvoton,npcm750-wdt"; interrupts = <GIC_SPI 47 IRQ_TYPE_LEVEL_HIGH>; reg = <0xf000801c 0x4>; clocks = <&clk NPCM7XX_CLK_TIMER>; };
