Potential patch for ov2640 with imx6

I have a ov2640 camera which did not work out of the box with the ov2640.c
mxc v4l2 driver in the linux-imx kernel. I have a patch for it to work with
i.mx6. My board is the sabrelite Would you accept it and is this the right
place to submit it?

Did you check if this had not been add in Boundary's tree already? I'd
update the kernel for their last release and check it before patching
it.

In either case please share your patch so we can review it and try to
get Boundary's input in it. This could allow it to be applied in their
tree :-)

Regards,

What MACHINE are you using?  It seems that the 'imx6qsabrelite' MACHINE
is deprecated and you should use 'nitrogen6x' from meta-fsl-arm-extra
This will use the Boundary Devices kernel which may already have the
change you are looking for.

In fact, currently, both are using the kernel. That's the reason we moved
it to -extra layer in dylan.

And it doesn't have support for the OV2640.

The kernel tree is the right place to merge the patch.

Ashwin, if you forward the patch to me and if it looks clean,
we'll be happy to include it in our tree. We probably won't
want to include it in the default kernel configuration, since
it's clearly not widely used.

Are you using another KLT camera module for the OV2640?
How difficult is it to glue up to the SABRE Lite/Nitrogen6X?

Please advise,


Eric
