driver-core: probe dependencies before probing
Before actually probing a device, find out what dependencies it has and
do our best to ensure that they are available at this point.
This is accomplished by finding out what platform devices need to be
probed and probing them. Non-platform devices will be probed when the
closest ancestor that is a platform device is probed.
If any dependencies are still unavailable after that (most probably a
missing driver or an error in the HW description from the firmware), we
print a nice error message so that people don't have to add a zillion of
printks to find out why a device asked for its probe to be deferred.
Dependencies are discovered with the help of the code that is already
implementing the specification of the firmware bindings, via the
callbacks registered with fwnode_add_dependency_parser().
Currently the dependencies list is discarded but it could be stored for
later usage.

Cover-letter:
Discover and probe dependencies
Hi,
this is version 2 of a series that probes devices in dependency order so
as to avoid deferred probes. While deferred probing is a powerful
solution that makes sure that you eventually get a working system at the
end of the boot, can make it very time consuming to find out why a
device didn't probe and can also introduce big delays in when a device
actually probes by sending it to the end of the deferred queue.
So far I have only tested on a Tegra124 Chromebook.
Thanks,
Tomeu

- Allocate the list of dependencies and pass it to the function that
fills it.

driver-core: probe dependencies before probing
Before actually probing a device, find out what dependencies it has and
do our best to ensure that they are available at this point.
This is accomplished by finding out what platform devices need to be
probed and probing them. Non-platform devices will be probed when the
closest ancestor that is a platform device is probed.
If any dependencies are still unavailable after that (most probably a
missing driver or an error in the HW description from the firmware), we
print a nice error message so that people don't have to add a zillion of
printks to find out why a device asked for its probe to be deferred.
Dependencies are discovered with the help of the code that is already
implementing the specification of the firmware bindings, via the
callbacks registered with fwnode_add_dependency_parser().
Currently the dependencies list is discarded but it could be stored for
later usage.

Cover-letter:
Discover and probe dependencies
Hi,
this is version 2 of a series that probes devices in dependency order so
as to avoid deferred probes. While deferred probing is a powerful
solution that makes sure that you eventually get a working system at the
end of the boot, can make it very time consuming to find out why a
device didn't probe and can also introduce big delays in when a device
actually probes by sending it to the end of the deferred queue.
So far I have only tested on a Tegra124 Chromebook.
Thanks,
Tomeu

- Allocate the list of dependencies and pass it to the function that
fills it.
