iio: adc: Add QCOM SPMI PMIC5 GEN3 ADC driver 



Add support for QCOM SPMI PMIC5 GEN3 ADC driver that supports
hardware based offset and gain compensation.
The ADC peripheral can measure both voltage and current
channels whose input signal is connected to the PMIC ADC AMUX.

The PMIC5 GEN3 ADC peripheral uses registers defined in SDAM.
The register set and configuration have been refreshed compared
to the prior QCOM PMIC7 ADC family.

	  This is the IIO Voltage PMIC5 Gen3 ADC driver for Qualcomm Technologies Inc.



	  The driver supports multiple channels read. The ADC is a 16-bit

	  sigma-delta ADC. The hardware supports calibrated results for

	  conversion requests and clients include reading voltage phone

	  power, on board system thermistors connected to the PMIC ADC,

	  PMIC die temperature, charger temperature, battery current, USB voltage

	  input, voltage signals connected to supported PMIC GPIO inputs. The

	  hardware supports internal pull-up for thermistors and can choose between

	  a 100k, 30k and 400k pull up using the ADC channels.



	  To compile this driver as a module, choose M here: the module will

	  be called qcom-spmi-adc5-gen3.
