[RFC PATCH 0/2] doc: sphinx: Add sphinx-prompt

[Nishanth Menon]

Add Sphinx-prompt for more readable documentation and yet is
userfriendly for people to copy paste.

See https://lore.kernel.org/all/87fs48rgto.fsf@baylibre.com/

If this approach looks correct, please ack and I can convert the
doc/board/ti/*.rst segments off to prompt instead of code-block where
applicable.

We copied our conf.py from kernel.org. Please, check if it can be added 
upstream.

/linux$ scripts/get_maintainer.pl Documentation/conf.py
Jonathan Corbet <corbet@lwn.net> (maintainer:DOCUMENTATION)
linux-doc@vger.kernel.org (open list:DOCUMENTATION)
linux-kernel@vger.kernel.org (open list)
bpf@vger.kernel.org (open list:BPF [MISC])

Does the extension exist on their minimum Sphinx version (1.7) or at 
least on the 2.24 in Documentation/requirements.txt?

Best regards

Trying things out, looks like sphinx-prompt 1.5.0 will work with 2.4.4
as well.

I am just a sphinx newbie.. I can propose, but taking the job up of a
massive Documentation cleanup across kernel documentation is a bit
beyond my availability.

If you think this is the way forward, then I can propose to the kernel
list.
