Subject: [PATCH v3 0/2] Intial support for voltage ADC

Changes since v2:

 - fixes per comments from Hartmut Knaack and Jonathan Cameron.
 - now register through IIO core only ADC channels described in DT.
 - register TEMP_DIE channel as IIO_TEMP type and as processed return value.
 - implement INFO_RAW and INFO_SCALE masks support in order to avoid losing 
   ADC precision.
 - various cleanups.

-------------------------------------------------------------------------------
Changes since v1:

 - the review comments from Peter Meerwald and Hartmut Knaack are taken into
   account
 - the driver private sysfs attributes are dropped out.
 - dt binding document is changed in the section of adc channel nodes - now the
   adc channel number is represented by "reg" property.
 - various cleanups found during preparation of version 2.

-------------------------------------------------------------------------------
Introduce inital support for VADC inside Qualcomm SPMI PMICs.
The vadc driver is reworked version of the same downstream
driver but now it is implemented through Industrial IO core.
