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 > -- > 2.46.1 >
