+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).
+
+Example:
+
+timer@f00080c1 {
+ compatible = "nuvoton,npcm750-wdt";
+ interrupts = <GIC_SPI 47 IRQ_TYPE_LEVEL_HIGH>;
+ reg = <0xf00080c1 0x4>;
+ clocks = <&clk NPCM7XX_CLK_TIMER>;
+};
