Hello, 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  and command DB driver  which are both still undergoing review. Changes since v1 : - Addressed review feedback from Doug, Mark, and Stephen - Replaced set_voltage()/get_voltage() callbacks with set_voltage_sel()/ get_voltage_sel() - Added set_bypass()/get_bypass() callbacks for BOB pass-through mode control - 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 Thanks, David : https://lkml.org/lkml/2018/4/5/480 : https://lkml.org/lkml/2018/4/10/714 : https://lkml.org/lkml/2018/3/16/1431 David Collins (2): regulator: dt-bindings: add QCOM RPMh regulator bindings regulator: add QCOM RPMh regulator driver .../bindings/regulator/qcom,rpmh-regulator.txt | 207 +++++ drivers/regulator/Kconfig | 9 + drivers/regulator/Makefile | 1 + drivers/regulator/qcom_rpmh-regulator.c | 910 +++++++++++++++++++++ .../dt-bindings/regulator/qcom,rpmh-regulator.h | 36 + 5 files changed, 1163 insertions(+) create mode 100644 Documentation/devicetree/bindings/regulator/qcom,rpmh-regulator.txt create mode 100644 drivers/regulator/qcom_rpmh-regulator.c create mode 100644 include/dt-bindings/regulator/qcom,rpmh-regulator.h -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project
