dt-bindings:iio:adc:qcom,spmi-iadc: txt to yaml format conversion. 



Straight forward conversion.  Not heard from Ivan in a while so if the
email bounces, I'll change the maintainer to myself for this binding unless
anyone else comes forwards.

Qualcomm's SPMI PMIC current ADC



QPNP PMIC current ADC (IADC) provides interface to clients to read current.

A 16 bit ADC is used for current measurements. IADC can measure the current

through an external resistor (channel 1) or internal (built-in) resistor

(channel 0). When using an external resistor it is to be described by

qcom,external-resistor-micro-ohms property.



IADC node:



- compatible:

    Usage: required

    Value type: <string>

    Definition: Should contain "qcom,spmi-iadc".



- reg:

    Usage: required

    Value type: <prop-encoded-array>

    Definition: IADC base address and length in the SPMI PMIC register map



- interrupts:

    Usage: optional

    Value type: <prop-encoded-array>

    Definition: End of ADC conversion.



- qcom,external-resistor-micro-ohms:

    Usage: optional

    Value type: <u32>

    Definition: Sense resister value in micro Ohm.

                If not defined value of 10000 micro Ohms will be used.



Example:

	/* IADC node */

	pmic_iadc: iadc@3600 {

		compatible = "qcom,spmi-iadc";

		reg = <0x3600 0x100>;

		interrupts = <0x0 0x36 0x0 IRQ_TYPE_EDGE_RISING>;

		qcom,external-resistor-micro-ohms = <10000>;

		#io-channel-cells  = <1>;

	};



	/* IIO client node */

	bat {

		io-channels = <&pmic_iadc  0>;

		io-channel-names = "iadc";

	};
