v1:
https://patchwork.linuxtv.org/project/linux-media/list/?series=7249

A branch for testing based on the most recent media-master is available at
https://git.sr.ht/~jmondi_/linux #jmondi/media-master/ov5640-v2

If anyone with a DVP setup could verify I have not broken their use case
I would very much appreciate that :)

v1 -> v2:
- rework the modes definition to process the full pixel array
- rework get_selection to report the correct BOUND and DEFAULT targets
- implement init_cfg
- minor style changes as suggested by Laurent
- test with 1 data lane

Thanks

Not on DVP mode I'm sorry :(

That's great, thanks for testing.

I think it's good enough making sure I have not broke DVP.

As you can see the driver now behaves in two different ways in DVP and
MIPI mode. The DVP works as it used to, and the framerate is
controlled by s_frame_interval, the frame size is fixed and the PCLK
is computed dyanically to accomodate the required FPS. In MIPI mode the
framerate is controlled by changing the vertical blankings. To each
mode a pixel rate is assigned and userspace changes the frame duration
by changing blankings. The most obvious gain is that the frame rate is
controllable in a continuous interval instead of being limited to a
few fixed values. It is my understanding that all drivers should be
moved to this model and s_frame_intervall should be dropped, but
unfortunately some bridge drivers in mainline still deman that.

If you are interested, I think the DVP mode should be moved to use the
same mecahnism as MIPI mode. I can't test so I haven't done so in this
series.

For now I think it's enough to make sure there are no regressions in
DVP mode.

For the tag, I think it would be appropriate to add it to the
following one:

91ae667b0d47 media: ov5640: Limit frame_interval to DVP mode only

RGB888 is weird on both the platforms I've tested on and I cannot get
colors right. Does your platform support RGB888 ?

Hi Jacopo,

I tested again without your series, and I can capture YUYV directly 
@1280x720 , which does not work anymore with your patches.

The image has some bad pixels in it, but still, capture is pretty good. 
I am not sure whether it's a timing problem on capturing pixels, I 
uploaded it here so you can have a look :

Could you try to revert these two ? I'm reworking the series and
knowing where I break DVP might be useful. In example, I think if:

82aebf4b7314 media: ov5640: Rework analog crop rectangles

is harmless it should be kept for DVP as well.
