How to handle v4l1 -> v4l2 driver transition

Hi all,

I've recently been working on adding support for cams with the ov511(+) and ov518(+) to the gspca ov519 driver. I'm happy to announce that work is finished, see:
http://linuxtv.org/hg/~hgoede/gspca

And the pull request I just send. This does lead to the question what to do with the existing in kernel v4l1 ov511 driver, which claims to support these 2 bridges too (but since the decompression code has been removed actually only works with the 511 in uncompressed mode).

It is clear that the ov518 usb-id's should be removed from the ov511 driver. But that still leaves the ov511 support, we could just completely remove the ov511 driver, as the code in gspca should cover all supported devices (and his been tested with a few).

However the downside of removing it is that people who used to have a working ov511 setup now will need to have a (very recent) libv4l to keep their setup working.

So I guess that the best way forward is to mark the driver as deprecated now and remove it in say 2 releases?

Regards,

Hans

It seems a good strategy to me, provided that all USB ID's found at the original ov511 are also present on gspca.

If so, please send the deprecate patch as well. I'll add it on my -git tree.

Cheers,
