Hi Mirian,

Thanks for your intrest!

That's easy enough, we can do it.

I think it should have a sysfs property allowing to change it and also set
the most reasonable value at probe.

I have actually a better idea: the friend of mine with the actual hardware
has discovered that a recent firmware update changed things and he
tasked an llm to properly handle the apex 6.

Since you two have the whole range of hardware and SDL has working
code why don't you take over? It would surely be better than me making
the bridge since you do own hardware and care about it.

Let me know if you are interested and I will be more than happy to
make that happen!

Best regards,
Denis
