As far as I know Renesas (or at least the kernel upstream team) doesn't
care. The driver is only used on five SH boards, I'd also say it can be
removed.

- atmel-isi: ATMEL Image Sensor Interface (ISI)
I believe this is still actively maintained. Would someone be
willing to convert this? It doesn't look like a complex driver.
That would be nice, I would like to avoid dropping this one.
Thanks for clarifying the state of the CEU driver. I did say, that I am
fine with dropping soc-camera gradually, and I stay with that. But I see
now, that at least two drivers want to stay active: Atmel ISI and PXA270.
One possibility is of course to make them independent drivers. If people
are prepared to invest work into that - sure, would be great! If we
however decide to keep soc-camera, I could propose the following: IIUC,
the largest problem is sensor drivers, that cannot be reused for other
non-soc-camera bridge drivers. The thing is, out of all the sensor drivers
currently under drivers/media/i2c/soc_camera only a couple are in use on
those active PXA270 and Atmel boards. I could propose the following:
1. Remove all bridge drivers, that noone cares about.
2. If anyone ever needs to use any of soc-camera-associated sensor
drivers, take them out of soc-camera and _remove_ any soc-camera
dependencies
3. If any soc-camera boards will need that specific driver, which in
itself is already unlikely, we'll have to fix that by teaching
soc-camera to work with generic sensor drivers!
That sounds like a good plan.
Ludovic, any chance someone at Atmel could convert the ISI driver ?
I add Songjun to the cc list. I think he has in mind to do this
conversion.
Songjun, can you confirm?

Laurent, I will take the ISI driver, convert it from soc_camera to V4L2.

Ludovic
