The problem is that *I* have no control over user space. But I also don't want
to say to my users "that is not my problem - get it solved yourself". This does
not help them.

Stuffing things into the kernel because the user space of a given
platform can't get itself organised isn't helpful to the other billion
plus Linux devices out there.

The assumption that there is  "the" user space of a given platform is wrong.

I'm a bit surprised at the arguments being exchanged here regarding
why the kernel may or may not deal with the detail that a (say) BT
chip is behind a uart.

I would have expected that the main (and IMO sufficient) reason why
the kernel should do it is because the particular bus used to connect
a BT chip to the CPU is a hw detail that a kernel that does its job
should keep to itself. Same as userspace not needing to care if a BT
chip is behind SDIO or USB, why does it have to tell the kernel behind
which UART a BT chip is sitting?
