+	  IIO Voltage PMIC5 Gen3 ADC driver for Qualcomm Technologies Inc.
+
+	  The driver supports reading multiple channels. The ADC is a 16-bit
+	  sigma-delta ADC. The hardware supports calibrated results for
+	  conversion requests and clients include reading phone power supply
+	  voltage, on board system thermistors connected to the PMIC ADC,
+	  PMIC die temperature, charger temperature, battery current, USB
+	  voltage input and voltage signals connected to supported PMIC GPIO
+	  pins. The hardware supports internal pull-up for thermistors and can
+	  choose between a 30k, 100k or 400k ohm pull up using the ADC channels.
+
+	  In addition, the same driver supports ADC thermal monitoring devices
+	  too. They appear as thermal zones with multiple trip points. A thermal
+	  client sets threshold temperature for both warm and cool trips and
+	  gets updated when a threshold is reached.
+
+	  To compile this driver as a module, choose M here: the module will
+	  be called qcom-spmi-adc5-gen3.
