Are you planning on fleshing out this > patch to address that issue? There was some more discussion about it, which can be found in the following thread: https://lists.ozlabs.org/pipermail/devicetree-discuss/2013-June/036934.html That's one of the last messages and it should have most of the background. If not you may have to walk up the thread for more context. In a nutshell I raised the question as to why we can't simply call of_platform_populate() earlier and side-step all the workarounds that have found their way into the kernel to side-step the issue of their not being a struct device associated with the struct device_node. If of_platform_populate() can be made to run early, then we can restore a whole lot of consistency in how "early" drivers on an OF kernel work. Thierry
