Let's convert this devicetree binding to YAML, to make it easier to
extend later.

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, or

                    "nuvoton,wpcm450-timer" for Hermon WPCM450.

- reg             : Offset and length of the register set for the device.

- interrupts      : Contain the timer interrupt of timer 0.

- 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>;

};
