+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.
+
+Required Node in the NPCM7xx BMC:
+An additional register is present in the NPCM7xx SOC which is
+assumed to be in the same device tree, with and marked as
+compatible with "nuvoton,npcm750-rst".
+
+Example:
+
+adc: adc@f000c000 {
+ compatible = "nuvoton,npcm750-adc";
+ reg = <0xf000c000 0x8>;
+ interrupts = <GIC_SPI 0 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&clk NPCM7XX_CLK_ADC>;
+};
+
+rst: rst@f0801000 {
+ compatible = "nuvoton,npcm750-rst", "syscon",
+ "simple-mfd";
+ reg = <0xf0801000 0x6C>;
+};
