Hi,
I'm trying to add support for YUV420 format to mx2_camera.c soc-camera

In my system, an imx27_visstrim_m10 board, this host is connected to a

OK,
thank you for your interest, it seems quite clear to me now.
However, I'll wait to see what Sascha has to say about this to avoid

Hi, Laurent.
How is it going?
Is there any chance these changes to be included for next release?
We are afraid that changes in the framework may

Hi,
they are currently sitting in Laurent's tree. According to him, there
are a couple of things that must be fixed before submitting them to

If you, Sascha, or someone else comes up with some requests or fixes
to the new series I don't mind to rebase it so you can just ignore
this patch, since I would have to sent a v2 version of the series
anyway.
Regards.

This doesn't look right. You already have || buf-state ==
MX2_STATE_ACTIVE above, so, this latter condition is never entered?
Yeah, I'm probably breaking m25 support here. This will be fixed in
the following version of my patches.

IRQs when the device is not streaming. This also makes the driver
return 0 as the sequence number of the first frame.
