[PATCH v2 0/2] regulator: add QCOM RPMh regulator driver


This patch series adds a driver and device tree binding documentation for
PMIC regulator control via Resource Power Manager-hardened (RPMh) on some
Qualcomm Technologies, Inc. SoCs such as SDM845.  RPMh is a hardware block
which contains several accelerators which are used to manage various
hardware resources that are shared between the processors of the SoC.  The
final hardware state of a regulator is determined within RPMh by performing
max aggregation of the requests made by all of the processors.

The RPMh regulator driver depends upon the RPMh driver [1] and command DB
driver [2] which are both still undergoing review.

Changes since v1 [3]:
 - Addressed review feedback from Doug, Mark, and Stephen
 - Replaced set_voltage()/get_voltage() callbacks with set_voltage_sel()/
 - Added set_bypass()/get_bypass() callbacks for BOB pass-through mode
 - Removed top-level PMIC data structures
 - Removed initialization variables from structs and passed them as
   function parameters
 - Removed various comments and error messages
 - Simplified mode handling
 - Refactored per-PMIC rpmh-regulator data specification
 - Simplified probe function
 - Moved header into DT patch
 - Removed redundant property listings from DT binding documentation
