Unfortunately my client wants to stick with the vendor kernel, so my only chance is to see whether it works with upstream mainline and if so, at least I know the hardware is OK. Why oh why do we have vendor kernels? In small-system's Linux there sooo many vendor kernels. Very hard to understand. It's 2023. The answers to a similar problem I found in the NXP community board was: go look at the driver source and see what's wrong. Thanks again for your answers. best regards, -- Patrick.
