+Nuvoton NPCM7xx timer
+
+Nuvoton NPCM7xx have three timer modules, each timer module provides five 24-bit
+timer counters.
+
+Required properties:
+- compatible : "nuvoton,npcm750-timer" for Poleg NPCM750.
+- reg : Offset and length of the register set for the device.
+- interrupts : Contain the timer interrupt with flags for
+ falling edge.
+- clocks : phandle of timer reference clock (usually a 25 MHz clock).
+
+Example:
+
+timer@f0008000 {
+ compatible = "nuvoton,npcm750-timer";
+ interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_HIGH>;
+ reg = <0xf0008000 0x50>;
+ clocks = <&clk NPCM7XX_CLK_TIMER>;
+};
