LTS for linux 5.15

I have updated the yocto submodules for yocto 4.0.25 to this list.

I have a 5.15.71 kernel that my recipes call for. When I build it two drivers fail to make it into the build. One is n_hdlc and the other is the sdma firmware. When the system boots it complains about the SDMA with this error.

[ 0.259634] imx-sdma 20ec000.dma-controller: Direct firmware load for imx/sdma/sdma-imx6q.bin failed with error -2
[ 0.259664] imx-sdma 20ec000.dma-controller: Falling back to sysfs fallback for: imx/sdma/sdma-imx6q.bin

I'm guessing I need to update the kernel to a later version but I don't know which one. How can I find that?

Hi,

Thank you for your interest in NXP Semiconductor products,

The issue is likely to porting issues, I will point a couple posts for you to review your built image. But the recommendation would be to use the NXP BSP manifest and add your extra submodules.
