I'm a little suspicious about this statement. I believe the Hantro combo is
identical to RK3399 and that you are confusing with Rockchip JPEG encoder here.
Here's the source of my suspicion:

https://github.com/JeffyCN/rockchip_mirrors/blob/mpp/osal/mpp_soc.cpp#L637

As this get burnt into DT, we really need to get this right. Perhaps we need to
run the reference software to verify ? Ping me if you need help with that.
