I currently modeled them as two regulator-fixed nodes because these are two distinct rails. Would you prefer modelling a single regulator node that controls the shared GPIO as below: wifi_en: regulator-wifi-en { compatible = "regulator-fixed"; regulator-name = "wifi_en"; gpio = <&tlmm 91 GPIO_ACTIVE_HIGH>; enable-active-high; pinctrl-0 = <&wifi_reg_en_pins_state>; pinctrl-names = "default"; regulator-boot-on; regulator-always-on; }; >> + >> +&apps_rsc { >> +    regulators-0 { >> +        compatible = "qcom,pm8150-rpmh-regulators";
