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

What is this based on? I'm not able to apply. "error: sha1 information

Answering to myself: The branch url above had an extra #, so my git 
fetch didn't get the right branch. And in that branch there's an extra 
commit that this series was based on.

You could rather point to lore.kernel.org, so that the intro letter and 
the discussions are also visible.

Very nice! I tested this on TI's DRA76 EVM (CSI-2). UYVY and RGB565, 
with the following resolutions: 160 120, 176 144, 320 240, 640 480, 720 
480, 720 576, 1024 768, 1280 720, 1920 1080.

All work. The only issue I saw was that with 1024x768 and 1280x720 
there's a thin vertical purple column on the right edge.

Great! A 2 data lanes setup I assume ? Have you been able to test the
framerate as well ?

Argh, you're right.
I'll see if I can fix them!

Yes, 2 data lanes. I can see that with 640x480 and 1024x768 I get ~30fps.

Why does ov5640_enum_frame_interval() return an error if ov5640 is a csi 
sensor?

Ah, never mind. I see the patch 18.

Thanks for spotting.

I've sent a v2.1 version of "media: ov5640: Rework analog crop rectangles"
where I have re-introduced the crop rectangles as they were defined in
the register tables for 1024x768 and 1280x720, which are closer to
what the datasheet suggests. The vertical purple column seems to be
gone now.

Thanks

I started testing this on my bench.
So far things look good.

To be able to test this, I have to revert this patch :
"media: i2c: ov5640: Remain in power down for DVP mode unless streaming"

Otherwise the sensor will not power up when starting streaming.


I have tested several formats, as you worked more on this sensor, could 
you tell me, does format YUYV_2x8 work in parallel mode at 1920x1080 or 
1024x768 ?
I managed to get it working fine at 640x480 .

The sensor looks to report valid framesizes for this mbus code :

# v4l2-ctl -d /dev/v4l-subdev1 --list-subdev-mbus-codes

#

but the ISC does not receive any frames at 1024x768 and 1920x1080.


What I can say is that the raw bayer format works at 1920x1080 , frames 
are received correctly.

Thanks,
Eugen

I never tested the sensor driver with a parallel setup I'm afraid.
The idea behind this series is that DVP shouldn't be affected and
continue working like it did.

Are 1080p and 1024x768 working without this series applied on your
setup ?

Thanks again for testin!

Hi Jacopo,

I was hoping that you had more information about the driver than myself.
I can tell that the parallel mode is not affected by your series from 
what I've seen so far.

I remember they weren't working before either.

I don't know exactly to which patches to add my Tested-by , as I have 
not tested the explicit patch behavior for each patch (e.g. where you 
add HBLANK control, I have not tested that ).

Is there something particular you would like me to try , except my usual 
image captures ?

Not on DVP mode I'm sorry :(

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 ?

I found one change, before your series, I could attempt to capture BGGR 
@ 640x480, now it looks to be gone :

Before:

# v4l2-ctl -d /dev/v4l-subdev1 --list-subdev-framesizes pad=0,code=0x3001
ioctl: VIDIOC_SUBDEV_ENUM_FRAME_SIZE (pad=0)
         Size Range: 160x120 - 160x120
         Size Range: 176x144 - 176x144
         Size Range: 320x240 - 320x240
         Size Range: 640x480 - 640x480
         Size Range: 720x480 - 720x480
         Size Range: 720x576 - 720x576
         Size Range: 1024x768 - 1024x768
         Size Range: 1280x720 - 1280x720
         Size Range: 1920x1080 - 1920x1080
         Size Range: 2592x1944 - 2592x1944


After:

# v4l2-ctl -d /dev/v4l-subdev1 --list-subdev-framesizes pad=0,code=0x3001
ioctl: VIDIOC_SUBDEV_ENUM_FRAME_SIZE (pad=0)
         Size Range: 1280x720 - 1280x720
         Size Range: 1920x1080 - 1920x1080
         Size Range: 2592x1944 - 2592x1944


However trying it without your patches, it doesn't work , I don't 
receive frames, and I can't even set 1280x720 at all, I get -EINVAL

So I assume you have been reworking the frame sizes.

With your series, I have tested RGGB at 1280x720 , 1920x1080 .
I also tested YUYV at 640x480 and RGB565_LE at 640x480.

I can't go higher with the YUYV/RGB565, I don't receive frames anymore.
I can't go higher with the bayer to 2592x1944 . But this did not work 
before your patches either.

I can't test this one unfortunately. It's a 1X24 . I have only 8 bits 
connected, so unless you can make this a 3x8 , there isn't anything I 
can do.

Right... I'm limiting SRGGB formats to only resolutions > 1280x720

... they do not work for me either.

So if they were not working before, maybe it's right not to enumerate
them ?

Be aware that DVP mode prevents you from setting a format if the
currently selected framerate is said to be "not supported" for that
format

Ah, I wonder if
07b49ac59fd9 media: ov5640: Fix durations to comply with FPS
82aebf4b7314 media: ov5640: Rework analog crop rectangles

Might have impacted DVP...

Should I keep separate fields for MIPI mode and leave the totals for
DVP untouched ?

Thanks again for your very useful testing

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 :

Hi again Eugen

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.

Thanks
