    1 Nuvoton NPCM Analog to Digital Converter (ADC)
    2 
    3 The NPCM ADC is a 10-bit converter for eight channel inputs.
    4 
    5 Required properties:
    6 - compatible: "nuvoton,npcm750-adc" for the NPCM7XX BMC.
    7 - reg: specifies physical base address and size of the registers.
    8 - interrupts: Contain the ADC interrupt with flags for falling edge.
    9 - resets : phandle to the reset control for this device.
   10 
   11 Optional properties:
   12 - clocks: phandle of ADC reference clock, in case the clock is not
   13                   added the ADC will use the default ADC sample rate.
   14 - vref-supply: The regulator supply ADC reference voltage, in case the
   15                            vref-supply is not added the ADC will use internal voltage
   16                            reference.
   17 
   18 Example:
   19 
   20 adc: adc@f000c000 {
   21         compatible = "nuvoton,npcm750-adc";
   22         reg = <0xf000c000 0x8>;
   23         interrupts = <GIC_SPI 0 IRQ_TYPE_LEVEL_HIGH>;
   24         clocks = <&clk NPCM7XX_CLK_ADC>;
   25         resets = <&rstc NPCM7XX_RESET_IPSRST1 NPCM7XX_RESET_ADC>;
   26 };
