This patch series adds a "post-init-supplier" device tree binding that
can be used to break dependency cycles in device tree and enforce a more
determinstic probe/suspend/resume order. This will also improve the
stability of global async probing and async suspend/resume and allow us
to enable them more easily. Yet another step away from playing initcall
chicken with probing and step towards fully async probing and
suspend/resume.

Patch 3 (the binding docunentation) provide a lot more details and examples.
