dt-bindings:iio:adc:nxp,lpc1850-adc yaml conversion 



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>;

};
