Hi Tim,
I am back at trying to get a proper image captured by the ADV7280 on
an imx6dl board connected to the parallel CSI bus.
I tried your patches against 5.4 and 5.12:

,but I am still getting horizontal scrolling images after running:
The analog camera I am using produces PAL content. If I force the
initial curr_norm to PAL like this:
diff --git a/drivers/media/i2c/adv7180.c b/drivers/media/i2c/adv7180.c
index e780969cc2f2..4ffe85ef02a0 100644

@@ -1346,7 +1346,7 @@ static int adv7180_probe(struct i2c_client *client,
state->irq = client->irq;

+ state->curr_norm = V4L2_STD_PAL;
if (state->chip_info->flags & ADV7180_FLAG_RESET_POWERED)
state->powered = true;
else
Then I get stable image and no more scrolling.
This patch from Steve is still needed though:

What would be the correct way to fix this NTSC versus PAL selection?
I tried passing the norm property like this, but it gives me an error:
# gst-launch-1.0 -v v4l2src norm=PAL device=/dev/video2 ! kmssink
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...

Appreciate any suggestions, thanks
I don't know much about the v4l/media subsystem, but in my case I was
able to switch to PAL like this:
v4l2-ctl --device /dev/v4l-subdev2 --set-standard PAL
Though your subdev is probably a different one as I was running this on
i.MX8MM without IPU.
