Hey, please don't blame pinctrl-cherryview until you actually know that
it causes the problem.

Also adding random parameters like "noacpi" to the command line is not
going to help at all in debugging this. So please do not alter the
command line. It only makes things worse.

Now, please send me your distro config (privately) and I'll try that
here if I can reproduce the problem.
