I've checked the docs for pm8009, the chip which also uses hfsmps515 regulators. The pdf clearly states that the 'Output voltage operating range' is from 2.8 V to 2.85 V. So we'd probably need to define different versions of HFS515 regulator data (like I had to create for pm8009-1).
.pmic_mode_map = pmic_mode_map_pmic5_smps, .of_map_mode = rpmh_regulator_pmic4_smps_of_map_mode, };
