Will the following solution work for your case?
Hello,
Finally we found the error. After a large comparison between the kernel source code of version 4.2 and 4.2.2, we noticed that the discontinuous_clk property on the device tree is being used. Previous versions bypassed the value from the device tree.
If someone is facing the same/similar error, please check the value of this property in the device tree. If it does not match the camera/driver configuration it will not receive buffers at all, and nothing can be debugged with the trace.
In…
If not, please provide more information including device tree node, v4l2-compliance test output, v4l2-ctl test output and checklist based on the following link. Thanks
