+Qualcomm's QPNP PMIC current ADC driver
+
+QPNP PMIC current ADC (IADC) provides interface to clients to read
+current. A 16 bit ADC is used for current measurements. There are multiple
+peripherals to the IADC and the scope of the driver is to provide interface
+for the USR peripheral of the IADC.
+
+IADC node
+
+Required properties:
+- compatible : should be "qcom,qpnp-iadc" for Current ADC driver.
+- reg : offset and length of the PMIC Aribter register map.
+- interrupts : The USR bank peripheral IADC interrupt.
+- qcom,adc-bit-resolution : Bit resolution of the ADC.
+- qcom,adc-vdd-reference : Voltage reference used by the ADC.
+- qcom,rsense : Internal rsense resistor used for current measurements.
+
+Channel node
+NOTE: Atleast one Channel node is required.
+
+Required properties:
+- label : Channel name used for sysfs entry.
+- qcom,channel-num : Channel number associated to the AMUX input.
+- qcom,decimation : Sampling rate to use for the individual channel measurement.
+ Select from the following unsigned int.
+ 0 : 512
+ 1 : 1K
+ 2 : 2K
+ 3 : 4K
+- qcom,pre-div-channel-scaling : Pre-div used for the channel before the signal
+ is being measured.
+- qcom,calibration-type : Calibration point values vary with temperature.
+ For improved accuracy fresh gain and offset point values
+ can be used for calibration. Reading fresh values for ever
+ read affects the reading time. Application can use the historic
+ values used from the trim register values.
+ Select from the following strings.
+ "absolute" : Uses TRIM gain and offset values for calibration.
+ "ratiometric" : Calculate the gain and offset calibration value when an ADC
+ request is issued.
+- qcom,scale-function : Scaling fuction used to convert raw ADC code to units specific to
+ a given channel.
+ Select from the following unsigned int.
+ 0 : Default scaling to convert raw adc code to voltage.
+ 1 : Conversion to temperature based on btm parameters.
+ 2 : Returns result in milli degree's Centigrade.
+ 3 : Returns current across 0.1 ohm resistor.
+ 4 : Returns XO thermistor voltage in degree's Centigrade.
+- qcom,hw-settle-time : Settling period for the channel before ADC read.
+ Select from the following unsigned int.
+ 0 : 0us
+ 1 : 100us
+ 2 : 200us
+ 3 : 300us
+ 4 : 400us
+ 5 : 500us
+ 6 : 600us
+ 7 : 700us
+ 8 : 800us
+ 9 : 900us
+ 0xa : 1ms
+ 0xb : 2ms
+ 0xc : 4ms
+ 0xd : 6ms
+ 0xe : 8ms
+ 0xf : 10ms
+- qcom,fast-avg-setup : Average number of samples to be used for measurement. Fast averaging
+ provides the option to obtain a single measurement from the ADC that
+ is an average of multiple samples. The value selected is 2^(value)
+ Select from the following unsigned int.
+ 0 : 1
+ 1 : 2
+ 2 : 4
+ 3 : 8
+ 4 : 16
+ 5 : 32
+ 6 : 64
