dt-bindings:iio:adc:cosmic,10001-adc yaml conversion 



I don't really know much about this one, hence the binding is
a simple conversion of what was in the txt file.

Note that I have taken on maintenance of this binding as I don't
have a recent address for Phani Movva.

Required properties:

  - compatible: Should be "cosmic,10001-adc"

  - reg: Should contain adc registers location and length.

  - clock-names: Should contain "adc".

  - clocks: Should contain a clock specifier for each entry in clock-names

  - vref-supply: The regulator supply ADC reference voltage.



Optional properties:

  - adc-reserved-channels: Bitmask of reserved channels,

    i.e. channels that cannot be used by the OS.



Example:

adc: adc@18101600 {

	compatible = "cosmic,10001-adc";

	reg = <0x18101600 0x24>;

	adc-reserved-channels = <0x2>;

	clocks = <&adc_clk>;

	clock-names = "adc";

	vref-supply = <&reg_1v8>;

};
