Greg,

This horse was beaten to death, can we please progress with this patch?
Create special topic branch or ack so I'll prepare this branch.

We are in -rc4 now and we (Mellanox) can't hold our submissions anymore.
My mlx5_core probe patches [1] were too intrusive and they are ready to
be merged, Parav's patches got positive review as well [2] and will be
taken next.

We delayed and have in our internal queues the patches for VDPA, eswitch
and followup for mlx5_core probe rework, but trapped due to this AUX bus
patch.

Thanks
