That is what i could understand from: _regulator_get in regulator/core.c Also, in the case of platform based boot, if the board init calls regulator_has_full_constraints which is anyways needed for the phy to probe correctly it will also return a dummy regulator. > >> +}; >> + >> &serial2 { >> pinctrl-names = "default"; >> pinctrl-0 = <&serial2_rxtx_pins>; >> diff --git a/arch/arm/boot/dts/da850.dtsi b/arch/arm/boot/dts/da850.dtsi >> index 33fcdce..ec2cec3 100644 >> --- a/arch/arm/boot/dts/da850.dtsi >> +++ b/arch/arm/boot/dts/da850.dtsi >> @@ -381,6 +381,14 @@ >> #phy-cells = <1>; >> status = "disabled"; >> }; >> + usb: usb@0225000 { > > > Don't need the leading 0 on usb@225000 > > The alias (usb:) might need to be more specific since there is a second usb > device that will be added later for musb.
