The names in the datasheet are vdd for the 1V0 supply and vddio for the
3V3 supply. I named the latter vdd2 instead because this device does not
have its own driver and instead it uses the onboard_usb_hub generic
driver, where the supplies are named vdd and vdd2.

Those are the names used for devm_regulator_bulk_get(). Is that not the
right way to match them?

Thank you and best regards,
