-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>;
-};
