Description
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 [1] 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.
