Like I asked already last time, AFAICS there is no upstream xr819
wireless driver in drivers/net/wireless directory. Do we still accept
bindings like this for out-of-tree drivers?
See esp8089.
There's also no in-tree driver for it.
The question is whether we should. The above might be a precedent, but
it may not necessarily be the way to go. The commit message for esp8089
seems to hint that there is intent to have an in-tree driver:
"""
Note that at this point there only is an out of tree driver for this
hardware, there is no clear timeline / path for merging this. Still
I believe it would be good to specify the binding for this in tree
now, so that any future migration to an in tree driver will not cause
compatiblity issues.

Regardless the bindings are in principle independent of the kernel and
just describing hardware. I think there have been discussions to move
the bindings to their own repository, but apparently it was decided
otherwise.
