I did not find anything in ePAPR, but chip-controller might be more
appropriate.

Looks like we need "simple-mfd" too in the compatible list?

I think we can also fold patch 5/5 into this patch and add the cfgchip
along with USB phy child node included.

If you respin the patch, I can drop 4/5 and 5/5 that I have queued and
included the updated patch instead.

Thanks,
