 Hello,
We are using Linux-CIP Kernel Version 4.19.140-cip33. We do not find IMX
files  in the Kernel supporting Camera Capture through CSI.Could you get
us  how the support can be added?
Thanks and Regards,
Rajashree Sankar

Can you be more specific about what kernel driver(s) you are missing? Is
latest 5.9 supporting this? Then please provide a reference (driver
name, DT bindings or even commit list).

Or are you referring to a feature of the vendor tree (linux-imx)? Then
please talk to NXP and ask about the status of this, if there is an
upstream equivalent by now or if this has been abandoned by them.

CIP has a strict upstream-first policy, so we can't take any downstream
patches. However, if a feature is upstream and only missed the latest
CIP kernel, you can propose backported patches for integration into that
kernel. Preconditions:

 - they are not invasive to other drivers or the kernel as a whole

 - you are a CIP member, or the CIP member community supports the
   backport (as it may increase our workload)

If configurable on your client, please disable this footer when posting
to public lists. It's irrelevant here because the content can't be
confidential due to the target public audience. This only bloats your

Hello Jan,
We have used Yocto Framework provided by NXP from the following link
<https://www.nxp.com/design/development-boards/i-mx-evaluation-and-development-boards/evaluation-kit-for-the-i-mx-6ull-and-6ulz-applications-processor:MCIMX6ULL-EVK?fpsp=1#documentsandsoftware>.Refer
to the Document L4.19.35_1.1.0_LINUX_DOCS
<https://www.nxp.com/webapp/Download?colCode=L4.19.35_1.1.0_LINUX_DOCS>  in
the above mentioned link.
The DT-bindings and the IMX Camera capture information will be available by
following the steps mentioned in the document
i.MX_Yocto_Project_User's_Guide from the above link.
The Kernel which we are using is fetched from the bitbake files attached
below( linux-yocto_4.19.bb and its append).Could you please let us know
whether CSI  Camera capture supported in this kernel be included in the
Linux CIP?

Thanks and Regards,
Rajashree Sankar

Hello Jan,

This is regarding requests for CSI support in the IMX processor.
We were using Yocto + NXP provided kernel to use the CSI peripheral of the
IMX6 processor. We have complete support from NXP for their kernel along
with the Yocto framework.
We want to move to CIP 4.19 + ISAR framework.
When we checked CIP kernel 4.19 - there was no support for CSI interface as
well as there were some differences in the arch support too.
After study of the NXP provided framework, we found that they use the
kernel from https://source.codeaurora.org/external/imx/linux-imx and commit
ID 0f9917c56d5995e1dc3bde5658e2d7bc865464de.
Even linux kernel 5.9 doesn't have the imx specific support.
Can you guide us on how we should proceed with the same - will it be
possible for CIP to add IMX support (or) should we request NXP to add the
patch for CIP kernel 4.19

Regards,
Lakshmi

That's unfortunate.

Yes, please reach out to NXP and ask what their answer for upstream is, 
today or at least for the future. It's their issue in the first place. 
Also for that, you should prepare with naming the kernel interfaces or 
drivers you need in more details.

If NXP cannot or do not want to answer this appropriately, plan B) will 
be identifying the patches they provide on top of the upstream kernel, 
optimally 4.19. Those patches then needs to be applied on top of the CIP 
kernel but, as they are unfortunately downstream only, you will then 
have to maintain them for your product and can't propose them for the 
CIP kernel.

Best regards,
Jan
