I made the entry like (added entry form smps10-out2-supply and smps10-in-supply in dt node) and then it failed. /*** + smps10-out2-supply = <&palmas_smps10_out2_reg>; + smps10-in-supply = <&tps65090_dcdc3_reg>; ldo3-in-supply = <&palmas_smps3_reg>; @@ -903,6 +905,20 @@ regulator-always-on; }; + palmas_smps10_out1_reg: smps10_out1 { + regulator-name = "smps10_out1"; + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; + regulator-always-on; + }; + + palmas_smps10_out2_reg: smps10_out2 { + regulator-name = "smps10_out2"; + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; + regulator-always-on; + }; + **/ After reversing the sequence, it worked fine.
