Nuvoton NPCM Analog to Digital Converter (ADC)
The NPCM ADC is a 10-bit converter for eight channel inputs.
Required properties:
- compatible: "nuvoton,npcm750-adc" for the NPCM7XX BMC.
- reg: specifies physical base address and size of the registers.
- interrupts: Contain the ADC interrupt with flags for falling edge.
Optional properties:
- clocks: phandle of ADC reference clock, in case the clock is not
added the ADC will use the default ADC sample rate.
- vref-supply: The regulator supply ADC reference voltage, in case the
vref-supply is not added the ADC will use internal voltage
reference.
Example:
adc: adc@f000c000 {
compatible = "nuvoton,npcm750-adc";
reg = <0xf000c000 0x8>;
interrupts = <GIC_SPI 0 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clk NPCM7XX_CLK_ADC>;
};
