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()/ 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 [1]: https://lkml.org/lkml/2018/5/9/729 [2]: https://lkml.org/lkml/2018/4/10/714 [3]: https://patchwork.kernel.org/patch/10348629 [4]: https://lkml.org/lkml/2018/5/11/696 [5]: https://lkml.org/lkml/2018/4/13/687 [6]: 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 | 208 +++++ drivers/regulator/Kconfig | 9 + drivers/regulator/Makefile | 1 + drivers/regulator/qcom-rpmh-regulator.c | 925 +++++++++++++++++++++ .../dt-bindings/regulator/qcom,rpmh-regulator.h | 36 + 5 files changed, 1179 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 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
