[PATCH v4 0/4] Add post-init-providers binding to improve suspend/resume stability

From: Saravana Kannan
Date: Wed Feb 21 2024 - 22:46:37 EST


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.

Patch 3 (the binding documentation) provides a lot more details and
examples.

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
