| H A D | fwnode.h | 8f486cab Thu Jun 23 03:03:42 CDT 2022 Saravana Kannan <saravanak@google.com> driver core: fw_devlink: Allow firmware to mark devices as best effort
When firmware sets the FWNODE_FLAG_BEST_EFFORT flag for a fwnode,
fw_devlink will do a best effort ordering for that device where it'll
only enforce the probe/suspend/resume ordering of that device with
suppliers that have drivers. The driver of that device can then decide
if it wants to defer probe or probe without the suppliers.
This will be useful for avoid probe delays of the console device that
were caused by commit 71066545b48e ("driver core: Set
fw_devlink.strict=1 by default").

This reverts commit 71066545b48e4259f89481199a0bbc7c35457738.
It causes boot problems on some systems, so revert it for now until it
is worked out.

Now that deferred_probe_timeout is non-zero by default, fw_devlink will
never permanently block the probing of devices. It'll try its best to
probe the devices in the right order and then finally let devices probe
even if their suppliers don't have any drivers.

Commit 71066545b48e ("driver core: Set fw_devlink.strict=1 by default")
enabled iommus and dmas dependency enforcement by default. On some
systems, this caused the console device's probe to get delayed until the
deferred_probe_timeout expires.
We need consoles to work as soon as possible, so mark the console device
node with FWNODE_FLAG_BEST_EFFORT so that fw_delink knows not to delay
the probe of the console device for suppliers without drivers. The
driver can then make the decision on where it can probe without those
suppliers or defer its probe.
