Add support for the Auxiliary Bus, auxiliary_device and auxiliary_driver. It enables drivers to create an auxiliary_device and bind an auxiliary_driver to it.
The bus supports probe/remove shutdown and suspend/resume callbacks. Each auxiliary_device has a unique string based id; driver binds to an auxiliary_device based on this id through the bus.

This patch is "To:" the maintainers that have a pending backlog of driver updates dependent on this facility, and "Cc:" Greg. Greg, I understand you have asked for more time to fully review this and apply it to driver-core.git, likely for v5.12, but please consider Acking it for v5.11 instead. It looks good to me and several other stakeholders. Namely, stakeholders that have pressure building up behind this facility in particular Mellanox RDMA, but also SOF, Intel Ethernet, and later on Compute Express Link.
I will take the blame for the 2 months of silence that made this awkward to take through driver-core.git, but at the same time I do not want to see that communication mistake inconvenience other parties that reasonably thought this was shaping up to land in v5.11.
I am willing to host this version at:
git://git.kernel.org/pub/scm/linux/kernel/git/djbw/linux tags/auxiliary-bus-for-5.11
...for all the independent drivers to have a common commit baseline. It is not there yet pending Greg's Ack.
Here is now a signed tag for everyone else to pull from and build on top of, for 5.11-rc1, that includes this patch, and the 3 others I sent in this series.
Please let me know if anyone has any problems with this tag. I'll keep it around until 5.11-rc1 is released, after which it doesn't make any sense to be there.
Thanks, pulled to mlx5-next
Jason, Jakob,
Can you please pull that mlx5-next branch to your trees? git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux.git
Thanks
