From my understanding, this smi register could clamp the dummy
commands after the larb power down for the sake of safe,
is it right?
If it's yes, I guess we could put this in the larb device's
runtime_resume/runtime_suspend callback.
we can enable the clamp in the larb's runtime_suspend and clear it in
the larb's runtime_resume.
then we don't need add "syscon" for smi-common node.
please tell me if I miss something.
Thanks.
