[PATCH v3 0/3] Add Broadcom iproc-static-adc controller driver

[Raveendra Padasalagi]

This patchset contains initial driver for Broadcom's
iproc static adc controller. The patchset is based on v4.7-rc1
tag and its tested on Broadcom Cygnus SoC.

The patches can be fetched from iproc-adc-v3 branch of
https://github.com/Broadcom/arm64-linux.git

Changes since v2:
 - Addressed various comments given by Jonathan Cameron and
   Peter Meerwald-Stadler on driver source code related to linux
   coding style and clean-up of code. Lot of source code change
   happened especially due to redefining the #defines.
 - Added code to support IIO_CHAN_INFO_SCALE mask to return
   scale value in iproc_adc_read_raw().
 - Removed #address-cells, #size-cells properties in DT binding
   document and dts file as adc will not have any child nodes as
   noticed by Rob Herring.

Changes since v1:
 - Modified Kconfig file to add more informative information
   in Broadcom Adc driver configuration menu.
 - Added Broadcom Adc driver menu config in the alphabetical
   order in Kconfig
 - Addressed various comments given by Peter Meerwald-Stadler
   on driver source code, Including issues related to linux
   coding style and race conditions.
