However, probing the SPMI hardware identification registers using the qcom_spmi-regulator driver reveals that the regulators in PM8909 are actually some kind of mixture between PM8916 and PM8226: - ult_lo_smps (= pm8916_buck_lvo_smps): s1 - ult_ho_smps (= pm8916_buck_hvo_smps): s2 - ult_nldo (= pm8916_nldo): l1, l2, l3, l10 - ult_pldo (= pm8916_pldo): l4, l8, l9, l12-l15, l17, l18 - pldo (= pm8226_pldo): l5, l6, l7, l11 Use this mapping to add the rpm_regulator_data for PM8909 by reusing the existing regulator definitions.
