Does this mean that if you don't provide the property or a GPIO it is tied high or High-Z? If so, please mention it here. More likely, given the context of this patch, no gpio and no tied low property means the driver should handle things as they used to be - but you should call that out in your commit message to be clear. > + > sd-vsel-gpios: > description: > GPIO that can be used to read the current status of the SD= _VSEL > --=20 > 2.46.1 >=20 --g0GmbFduZp5Hkvg7 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQRh246EGq/8RLhDjO14tDGHoIJi0gUCZ0ipagAKCRB4tDGHoIJi 0kCrAP9N2emwE+htZGNB9lvu6CN6KHjIRKADtq875PoNHM6XiAEAsv0/3ontG5XF 9k8wV2+utMVxbd5jyPMTnNbdx/PzkwA= =Uoob -----END PGP SIGNATURE----- --g0GmbFduZp5Hkvg7--
