Subject: [PATCH v1 0/4] Add post-init-supplier binding to improve
 suspend/resume stability

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.

Saravana Kannan (4):
  driver core: Adds flags param to fwnode_link_add()
  driver core: Add FWLINK_FLAG_IGNORE to completely ignore a fwnode link
  dt-bindings: Add post-init-supplier property
  of: property: fw_devlink: Add support for "post-init-supplier"
    property
