The GPIO polarity for onewire must be GPIO_ACTIVE_HIGH. On previous versions this used to work as it looks like the right flag values are being passed since : https://lists.denx.de/pipermail/u-boot/2020-April/407195.html And that series broke the old functionality for onewire nodes. Some boards had the correct value for the polarity, but it wasn't clear so I replaced it with the right macro for the flag, instead of an empty value.
