Ideally the properties at least would never change; we do have a common parser for the properties which is part of the patchset so in theory it would be possible to change the documentation in a backward-compatible way. I added these properties as well as all the other properties supported by the sensor driver are documented here. That has been the practice AFAIU, albeit omissions do happen occasionally. The issue I see with omitting the documentation here is that the user otherwise won't know whether a driver uses a given property or not: it shouldn't be necessary to read driver code to write DT source. -- Regards, Sakari Ailus e-mail: sakari.ailus@xxxxxx -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
