Hi Marcel,

One option is of course to keep the max-speed in the DT at 115200
Mbps. It would work, but seriously slow down the transport. Maybe
this should be done until we get access to the GPIOs.
So I am convinced when we run on hardware that has no GPIO resources
exposed (as it is with RPi right now), we should limit the
operational speed to the initialization speed. And then my problem
actually goes away. It also forces people to get the GPIOs exposed or
they have to stick with a slower HCI transport.
We may also reset to initialization speed on module unload.
This will allow multiple tests on the hardware, even if it does not
have GPIOs exposed.
I prefer this solution instead of coding workarounds within the devicetree.
Thanks
Stefan

Fred
