[PATCH v2 08/20] dt-bindings:iio:adc:nuvoton,npcm750-adc yaml conversion

Jonathan Cameron
2020-09-09T18:04:55Z

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Renamed the file to reflect the only compatible.
Added #io-channel-cells to make it easier to support consumers of the
ADC channels this device provides.

-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.
-- resets : phandle to the reset control for this device.
-
-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>;
- resets = <&rstc NPCM7XX_RESET_IPSRST1 NPCM7XX_RESET_ADC>;
-};
