It may make sense, but I have some comments about it:
1) v4l_experimental - I think we may just drop it. It was meant to be a
staging
area in the old days, but never worked. The 3 drivers there never suffered any
maintanership.
Even the firewire driver that used to be there were developed independently.
So, IMO, we can
just remove it and, if anyone needs those drivers, they can just look inside
the -hg history.
2) firmware - the code there is just what we have in kernel. While this
can be broken,
I can't see much sense, as I don't foresee any changes there: new firmwares are
going to
linux-firmware tree and have an upstream maintainership in separate;
3) media docs - the docs are part of upstream tree. So, it doesn't make
sense to have
a separate tree for it. IMO, the proper direction is to merge upstream the
capability of
automatic generation of some xml scripts (like videobuf2.h.xml). Yet, there are
a few files
present on v4l2-apps that are also converted to xml, as they are usage examples
at the API.
I'm not sure what to do with them.
4) v4l2-apps - I agree that splitting it could be a good idea, provided
that we find
a way to handle the few cases where we have "example" applications at the media
docs.

That's good! I always check if the -git compiles with x86_64, but I generally
don't check
all architectures on my checks.
Cheers,
Mauro.
