Greg,

Can you pull this in as part of your tree please?

Thanks, Saravana

This patch series adds a "post-init-providers" 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.

dtschema update for post-init-providers will have a more substantial
documentation of the examples and the need for this property.

v4->v5:
- As suggesed by reviewers, removed line wraps to go > 80 chars.
- Added Reviewed-by and Acked-by
- Dropped the DT schema documentation patch (will submit tha to dtschema)

v3->v4:
- Fixed MAINTAINERS file to go with the file rename.

v2->v3:
- Changes doc/code from "post-init-supplier" to "post-init-providers"
- Fixed some wording that was ambiguous for Conor.
- Fixed indentation, additionalProperies and white space issues in the
  yaml syntax.
- Fixed syntax errors in the example.

v1->v2:
- Addressed Documentation/commit text errors pointed out by Rob
- Reordered MAINTAINERS chunk as pointed out by Krzysztof
