when the VIR_LDO1 regulator supplier is it's brother, we can't find the supplier. example code : &vir_regulator { ldo0_vir: ldo0-virtual { regulator-compatible = "VIR_LDO0"; regulator-name= "VIR_LDO0"; regulator-min-microvolt = <1000000>; regulator-max-microvolt = <2000000>; }; ldo1_vir: ldo1-virtual { regulator-compatible = "VIR_LDO1"; regulator-name= "VIR_LDO1"; regulator-min-microvolt = <1000000>; regulator-max-microvolt = <3000000>; ldo1-supply = <&ldo0_vir>; }; ... } so we add the child ptah to find the suppier.
