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 On Tue, Oct 20, 2020 at 5:48 PM Rajashree Sankar < rajashree.sankar@sanmina.com> wrote: > 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 > >> >> -- CONFIDENTIALITY This e-mail message and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

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.
