    5 
    6 Required properties:
    7 - compatible      : "nuvoton,npcm750-timer" for Poleg NPCM750, or
    8                     "nuvoton,wpcm450-timer" for Hermon WPCM450.
    9 - reg             : Offset and length of the register set for the device.
   10 - interrupts      : Contain the timer interrupt of timer 0.
   11 - clocks          : phandle of timer reference clock (usually a 25 MHz clock).
   12 
   13 Example:
   14 
   15 timer@f0008000 {
   16     compatible = "nuvoton,npcm750-timer";
   17     interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_HIGH>;
   18     reg = <0xf0008000 0x50>;
   19     clocks = <&clk NPCM7XX_CLK_TIMER>;
   20 };
