[PATCH 0/3] iio: adc: Add support for QCOM SPMI PMIC7 ADC

From: Jishnu Prakash
Date: Tue Mar 24 2020 - 11:45:33 EST


The first patch converts the ADC DT bindings from .txt to .yaml format.

The second patch updates the documentation, for PMIC7 ADC. The main
difference between PMIC5 and PMIC7 for ADC is that for PMIC7, SW requests to
ADCs (on any PMIC) need to go through the ADC on PMK8350, which communicates with
the ADCs on other PMICs through PBS. A SID register has been added for SW to specify
the PMIC with which it needs to communicate.

The third patch adds driver support for PMIC7 ADC. It also adds definitions for
PMIC7 ADC channels and virtual channel definitions per PMIC (made by combining ADC
channel number and PMIC SID), to be used by ADC clients for PMIC7.
