I don’t see this anywhere in the 5.10 version, while it was there in the 4.19/preempt-rt. I suspect that means it’s a driver that was never upstreamed (or is still in the process of being upstreamed).

Is using the 4.19 kernel an option for you?

Does anyone from the kernel team know if there is a version of that driver for the 5.10 preempt-rt kernel?

Thanks,
