Yes. But this does not explain why this device is not found at all.
This would only result in an incorrect base-address. And this works

Its already there in the dtsi file. I've added it again in this
dts file as well.

Ah, this is helpful. Thanks. Here the output for your profound

Any more ideas? Can you send me the output of these *dump* functions
on the chromebook_jerry please?
Thanks,
