Looks like, so it needs bindings. Best regards, Krzysztof

Looks like, so it needs bindings. Ah, I see the patch now. Best regards, Krzysztof

The set of regulators available in the PM8909 PMIC is similar to PM8916 which is already supported by the driver. s3, s4 and l16 are missing. 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.
