[PATCH v2 3/5] regulator: qcom-rpmh: add support for pm8010 regulators

From: Fenglin Wu via B4 Relay
Date: Wed Dec 13 2023 - 21:59:20 EST


From: Fenglin Wu <quic_fenglinw@xxxxxxxxxxx>

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.
