Subject[PATCH v3 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. It also depends upon
two recent of_regulator changes: [3] and [4].

Changes since v2 [5]:
- Replaced '_' with '-' in device tree supply property names
- Renamed qcom_rpmh-regulator.c to be qcom-rpmh-regulator.c
- Updated various DT property names to use "microvolt" and "microamp"
- Moved allowed modes constraint specification out of the driver [4]
- Replaced rpmh_client with device pointer to match new RPMh API [1]
- Corrected drms mode threshold checking
- Initialized voltage_selector to -EINVAL when not specified in DT
- Added constants for PMIC regulator hardware modes
- Corrected type sign of mode mapping tables
- Made variable names for mode arrays plural
- Simplified Kconfig depends on
- Removed unnecessary constants and struct fields
- Added some descriptive comments

Changes since v1 [6]:
- 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
