On boards where these rails are software-controlled, probing the codec before the regulators are up results in -ENXIO errors during register access. This short series adds optional regulator support to both the device tree binding and the driver, so platforms that need explicit power sequencing can describe and enforce it: Link: https://patch.msgid.link/20260525-nau8822-reg-v2-0-7d37ae393e46@flipper.net --- a67c554dbc0fdd7e3c5909cb9f0fff41c51b2e9d
