iio: adc: Add ADC5 driver snapshot 



ADC5 peripheral is used by client to read VADC
channels. Clients include reading vph_pwr and on board
system thermistors used for thermal mitigation.
Register ADC5 peripheral with IIO framework.

This snapshot is taken as of msm-4.14
'commit <ab8d48dd> ("Merge "diag: Increase the
MHI buffer size to 4k"")'.

	  This is the IIO Voltage PMIC5 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.
