Hi,
I was trying ov5640 camera sensor with the mainline BSP 6.0.0-rc3 kernel
and it fails to works, while it works quiet well on v5.18. When I
bisect, it points out to this commit 1f391df4 (media: v4l2-async: Use
endpoints in __v4l2_async_nf_add_fwnode_remote()) by Laurent Pinchart
and this is what it says in the logs :
[ 4.291355] imx-ipuv3-csi imx-ipuv3-csi.0: Registered ipu1_csi0

[ 4.305228] imx-ipuv3 2400000.ipu: Registered ipu1_ic_prpenc capture

[ 4.414971] stmpe-adc stmpe-adc: DMA mask not set
So, now when I try to revert the change done by this commit, it still
fails. I assume there are a lot more changes following the commit that
could lead to this failure. Below are the logs.
Is there a way to get it to work without reverting any changes? Or Is
there something I'm missing or have to do any changes in the
corresponding files to get it to work?
