fw_devlink parses the firmware (device tree) to figure out device dependencies and uses that to enforce probe ordering and suspend/resume ordering between consumer and supplier devices. It is also used to implement sync_state() callbacks that let a supplier know when all its consumers have probed.
In this presentation, we'll talk about how some of the issues that were discussed in LPC 2021  have been resolved and any new issues that have come up. In addition, we'll discuss how we could use fw_devlink to enabled parallelized boot and suspend/resume by default for DT based systems.
