Those drivers are part of the legacy SoC camera framework.
They're being converted to not use it, but sometimes we're
keeping both legacy any new driver.

This time, for example, we have two drivers on media with
the same name: ov772x. That's bad.

So, in order to prevent that to happen, let's prepend the SoC
legacy drivers with soc_.

No functional changes.

Let's kill all of these in the next kernel. I see no reason for keeping
them around.

For now, let's just avoid the conflict if one builds both modules and
do a modprobe ov772x.

While people are doing those SoC conversions, I would keep it. We
could move it to staging, to let it clear that those drivers require
conversion, and give people some time to work on it.

In the specific case of ov772x, as we have already a driver that doesn't
require soc_camera, we can strip it for -next.

Which people are doing SoC conversions? Nobody is using soc-camera anymore.
It is a dead driver. The only reason it hasn't been removed yet is lack of
time since it is not just removing the driver, but also patching old board
files that use soc_camera headers. Really left-overs since the corresponding
soc-camera drivers have long since been removed.

There is nobody working on it. These are old sensors, and few will have
the hardware to test it. If someone needs such a sensor driver, then they
can always look at an older kernel version. It's still in git after all.

Just kill it rather then polluting the media tree.

I remember at least Jacopo has been doing some. There was someone else as
well, but I don't remember right now who it was. That said, I'm not sure if
there's anything happening to the rest.

Is there something that prevents removing these right away? As you said
it's not functional and people can always check old versions if they want
to port the driver to V4L2 sub-device framework.

Yes, I did port a few drivers and there are patches for others coming.

[PATCH v2 0/4] media: soc_camera: ov9640: switch driver to v4l2_async

All dependencies should have been solved so far, but given that
someone might want to do the porting at some point, I don't see how
bad would it be to have them in staging, even if people could look
into the git history...

The atomisp driver was removed on similar basis --- it was not functional
and no-one was actively working on it. And there was lots of work to keep
the codebase compiling (not as much the case with these drivers though).
I think that decision regarding atomisp was a correct one, and I don't see
much difference between that and these drivers.
