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()/ 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 [1]: https://lkml.org/lkml/2018/4/5/480 [2]: https://lkml.org/lkml/2018/4/10/714 [3]: 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
