These voltages are not a multiple of the given step-size 8000 (with base voltage 1664000) in pm8998_pldo, resulting in PLDO regulators l18 and l22 failing to validate and in turn not probing the rpm-pm8998-regulator driver: l18: unsupportable voltage constraints 2856000-2848000uV qcom_rpm_smd_regulator rpm-glink:rpm-requests:pm8998-regulators: l18: devm_regulator_register() failed, ret=-22 Round the voltages down for the sake of erring on the safe side, leaving a comment in place to document this discrepancy wrt downstream sources.
