I've already queued the patch for merging. But just for your background knowledge, and the various lists: the basic device integration data, whether in DT or in hwmod, should be decoupled from the existence of drivers. It should be possible to have a complete set of SoC integration data ready to integrate at the moment that a device is approved for upstreaming. That way, driver writers can simply write and merge their driver, with the minimum of patches to the integration data. Generally the people who work on device drivers aren't too familiar with SoC integration - they are focused on their specific IP blocks - so it makes sense to decouple these components. So: in the context of the present epwmss discussion, in an ideal world, we'd have DT entries for eQEP, even though there's no driver available yet. - Paul -- 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
