[PATCH v2 09/20] dt-bindings:iio:adc:nxp,lpc1850-adc yaml conversion

Jonathan Cameron

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

Most of the description in the original doc is effectively boilerplate
and does not bring much value so I have not carried it over into the yaml.

Added #io-channel-cells to simplify use of channels on this ADC by
consumer drivers.

-NXP LPC1850 ADC bindings

-Required properties:
-- compatible: Should be "nxp,lpc1850-adc"
-- reg: Offset and length of the register set for the ADC device
-- interrupts: The interrupt number for the ADC device
-- clocks: The root clock of the ADC controller
-- vref-supply: The regulator supply ADC reference voltage
-- resets: phandle to reset controller and line specifier
-
-Example:
-
-adc0: adc@400e3000 {
- compatible = "nxp,lpc1850-adc";
- reg = <0x400e3000 0x1000>;
- interrupts = <17>;
- clocks = <&ccu1 CLK_APB3_ADC0>;
- vref-supply = <&reg_vdda>;
- resets = <&rgu 40>;
-};
