| 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>; |
| }; |
