regulator: qcom-rpmh: add support for pm7550 regulators

2025-07-13T21:37:09Z

Add RPMH regulators exposed by Qualcomm Technologies, Inc. PM7550 PMIC. It has 6 FTS525 (FT-SMPS) and 23 LDOs with 3 different types. L1-L11 are LDO515 LV NMOS, L12-L13 are LDO515 MV PMOS, L14-L23 are LDO512 MV PMOS.

regulator: qcom-rpmh: Update ranges for FTSMPS525

2024-11-18T15:44:30Z

All FTSMPS525 regulators support LV and MV ranges; however, the boot loader firmware will determine which range to use as the device boots. Nonetheless, the driver cannot determine which range was selected, so hardcoding the ranges as either LV or MV will not cover all cases as it's possible for the firmware to select a range not supported by the driver's current hardcoded values. To this end, combine the ranges for the FTSMPS525s into one struct and point all regulators to the updated combined struct. This should work on all boards regardless of which range is selected by the firmware and more accurately caputres the capability of this regulator on a hardware level.

regulator: Unify "negative error number" terminology in comments

2024-08-29T13:20:30Z

Previous commits cleaning up kerneldoc used the term "negative error number" to refer to error condition return values. Update remaining instances of other terminology such as "error code" or "errno" as well so the whole regulator subsystem is unified.

regulator: qcom-rpmh: add support for pm8010 regulators

2023-12-14T10:57:01Z

Add RPMH regulators exposed by Qualcomm Technologies, Inc. PM8010 PMIC. It has 7 LDOs with 3 different types, LDO1 - LDO2 are L502 NMOS LDOs, LDO5 and LDO7 are L502 PMOS LDOs, LDO3/LDO4/LDO6 are L502 PMOS LDO for low noise applications. Also, LDO3 - LDO7 don't support LPM.
