2023-06-07regulator: qcom-rpmh: Fix regulators for PM8550Abel Vesa
The PM8550 uses only NLDOs 515 and the LDO 6 through 8 are low voltage type, so fix accordingly.

2023-03-24regulator: qcom-rpmh: Revert "regulator: qcom-rpmh: Use PROBE_FORCE_SYNCHRONOUS"Douglas Anderson
This reverts commit 58973046c1bf ("regulator: qcom-rpmh: Use PROBE_FORCE_SYNCHRONOUS"). Further digging into the problems that prompted the us to switch to synchronous probe showed that the root cause was a missing "rootwait" in the kernel command line arguments. Let's reinstate asynchronous probe.

2023-03-20regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers between 4.14 and 4.19Douglas Anderson
This follows on the change ("regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers that existed in 4.14") but changes regulators didn't exist in Linux 4.14 but did exist in Linux 4.19. NOTE: from a quick "git cherry-pick" it looks as if "bd718x7-regulator.c" didn't actually exist in v4.19. In 4.19 it was named "bd71837-regulator.c".

2018-08-10regulator: add QCOM RPMh regulator driverDavid Collins
Add the QCOM RPMh regulator driver to manage PMIC regulators which are controlled via RPMh on some Qualcomm Technologies, Inc. SoCs. 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. Add support for PMIC regulator control via the voltage regulator manager (VRM) and oscillator buffer (XOB) RPMh accelerators. VRM supports manipulation of enable state, voltage, and mode. XOB supports manipulation of enable state.
