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.
